MOTION FOR REHEARING
MANSFIELD, Judge.Gustavo Julian Garcia, appellant, was convicted of capital murder — murder intentionally committed in the course of committing or attempting to commit robbery1 — under Texas Penal Code § 19.03(a)(2) (1990). The jury answered the “deliberateness” and “future dangerousness” special issues (special issues one and two) under Texas Code of Criminal Procedure art. 37.071(b) (1990) in the affirmative and the third special issue (mitigation) in the negative, and punishment was assessed at death in accordance with Texas Code of Criminal Procedure art. 37.071(e) (1990).2
Automatic appeal was made to this Court which, on December 21, 1994, reversed the judgment of the trial court and remanded the cause for a new trial. The State’s motion for rehearing was granted on February 8, 1995. We now affirm' the judgment of the trial court and will proceed to address appellant’s seventy points of error.
Statement of Facts
The evidence at trial established that on December 9, 1990 appellant and Christopher Vargas entered a liquor store, Beverage Warehouse, in the city of Plano. Appellant was armed with a single shot .20 gauge sawed-off shotgun and had additional shells in his possession. Appellant ordered the clerk, Craig Turski, to give him the money from the cash register. At the same time, Vargas took beer from the store and put it in their car. A female customer walked in the store, saw appellant, and immediately left.
Appellant shot Turski at close range in the abdomen. Turski fled outside the store, pursued by appellant. Appellant then reloaded the shotgun and shot Turski in the back of the head. The female customer, Donna De-lozier Sawtelle, subsequently returned to the store with her husband. Finding the store deserted, they called the police. Turski was found and was transported to the hospital, where he later died from gunshot wounds.
On January 5, 1991 at about 12:30 a.m., Vargas, appellant and appellant’s girlfriend (Sheila Phanae Loe) stopped at a Texaco station in Plano. While Loe pumped gas, appellant and Vargas entered the station with the same .20 gauge shotgun used to kill Turski. The clerk, Gregory Martin, was on the phone with his girlfriend. As he saw them enter, he informed her he thought he was about to be robbed and asked her to call the police. Martin was taken into a back room and shot at point blank range in the back of the head. He died at the scene.
Appellant claimed Vargas shot Martin. Evidence introduced at trial, however, indicated Vargas was carrying beer to their car (as he did in the earlier robbery) while appellant shot the clerk. In addition, the shotgun was found near the freezer in close proximity *384to appellant at the time of his capture. Two firearms experts testified at trial that the shotgun found at the scene of Martin’s murder was the same weapon used in Turski’s murder.
Alerted by Martin’s girlfriend, the police arrived at the scene to find appellant, Vargas and Loe still present, Vargas was found, unarmed, standing over Martin’s body. He claimed to have just entered the store and found Martin lying there. Appellant was found hiding in the freezer area close to where the shotgun was found.
Appellant was transported to the Plano Police Department. He was read his “Miranda” warnings repeatedly. He subsequently confessed, both orally and in writing, to the murders of both TursM and Martin. His confessions were videotaped, and a separate written confession was prepared for each offense.
Appellant’s written statement regarding the Mlling of TursM in its entirety reads as follows:
Det. Wilson is writing my statement. Approx. 3-4 weeks from today’s date, Chris Vargas & I robbed a liquor store & I killed the clerk. The liquor store was behind a 7-11 store at Plano Pkwy. & Ave. K. I was driving Sheila’s Chev. Monza. We waited in the liquor store parking lot until the customers all left. Both Chris & I pulled a 20 ga. sawed-off shotgun on the clerk. I had the clerk give me the money out of the cash register & it was about $500. Chris was grabbing up beer. Chris went outside to pull the car up to the front door. I had the clerk go into a little room next to the cash register & I had him get on his knees. A customer, a white woman walked in the store & saw me & she walked back out. I then panicked and I shot the clerk with the shotgun. The clerk started coming at me & threw a chair at me and then he ran outside. I loaded the shotgun & shot the clerk again outside the store. The clerk had jumped over the fence & was in some grass when I shot him the 2nd time. I then ran to the car & we drove off. I told Sheila my common-law wife about the robbery after we did it. End — G.G.
The statement was completed at 9:05 a.m. on January 5, 1991. Each page is signed by appellant and two witnesses. The statement was taken by Det. David Wilson of the Plano Police Department.
At the top of the first page of the statement appears the following:
I, the undersigned Gustavo Julian Garcia, am 18 years of age, having been born on 9-27-72 at_I now live at 804 N. Tennessee, McKinney, Tx. I have been duly warned and advised by Det. David Wilson, a person who has identified himself as an office of the Plano Police Department, that:
GG[ ] (1) I have the right to remain silent and not make any statement at all and any statement I make will be used against me at my trial.
GG[] (2) Any statement I make will be used as evidence against me in court.
GG[ ] (3) I have the right to have a lawyer present to advise me prior to an during questioning;
GG[] (4) If I am unable to employ a lawyer, I have the right to have a lawyer appointed (without cost to me) to advise me prior to and during my questioning; and
GG[ ] (4) [sic] I have the right to terminate the interview at any time.
Before each of the numbered warnings appear the initials “G.G.” These warnings are repeated on each page of the statement and the initials “G.G.” appear before each part of the warnings.
Finally, at the bottom of each page, immediately above appellant’s signature, appears the following:
I have read each page of this statement consisting of 2 page(s), each page of which bears my signature, and corrections, if any bear my initials, and I certify that the facts contained herein are true and correct. I further certify that I have made no request for the advice or presence of a lawyer before or during any part of this statement, nor at any time before it was finished did I request that this statement be *385stopped. I also declare that I was not told or prompted what to say in this statement.
At trial, an acquaintance of appellant, Bobby Flores, testified he was at Vargas’ house the night of the TursM murder. Flores testified that Vargas and appellant left the house and subsequently returned with beer and a lot of money. Flores asked appellant where he got the beer and money. Appellant in response stated he went into a store, took the beer and money, shot the clerk and left.
Appellant’s Points of Error
Appellant has raised seventy points of error, sixty-seven in his original brief and three in his first supplemental brief. On original submission, this court addressed and overruled appellant’s point of error number sixty-eight, in which he contends the evidence is insufficient to show Turski was killed during a robbery or attempted robbery as alleged in the indictment. This Court also addressed and overruled appellant’s points of error numbers sixty-nine and seventy in which he avers the evidence is insufficient to support the July’s affirmative answers as to the special issues. Tex.Code Crim.Proe. 37.071(b).
Our disposition of points of error numbers sixty-eight, sixty-nine and seventy is not disputed by the parties on rehearing and need not be readdressed.
This Court previously held that the trial judge erred in admitting appellant’s written statement as that statement was found to be not in compliance with Tex.Code Crim.Proe. art. 38.22, § 2(b). Specifically, we held that the statement failed to contain required language demonstrating that appellant knowingly, intelligently and voluntarily waived the rights described in Tex.Code Crim.Proe. 38.22, § 2(a) and which are delineated on each page of the statement. Furthermore, we held that the error was not harmless under Tex.Rule App.Proe. 81(b)(2).
In reversing appellant’s conviction for the above reason the Court sustained appellant’s point of error number forty-two. Accordingly, we will address appellant’s point of error number forty-two and related points of error numbers forty-three through fifty-one first.
I. Appellant’s Written Statement Substantially Complies with the Requirements of Art. 38.22, Sec. 2(b).
In points of error numbers forty-two through fifty-one, appellant asserts appellant’s written confession did not meet the requirements of Texas Code of Criminal Procedure article 38.22, § 2(b), and its admission was thus erroneous. Appellant also asserts appellant’s written confession was taken in violation of his right to effective assistance of counsel under both the Texas and United States Constitutions, in violation of his right against self-incrimination under both constitutions and in violation of his due process rights under the United States Constitution. We will address these points of error collectively.
Texas Code of Criminal Procedure article 38.22, § 2(a) and 2(b) in their entirety are as follows:
See. 2. No written statement made by the accused as a result of custodial interrogation is admissible as evidence against him in any criminal proceeding unless it is shown on the face of the statement that:
(a) the accused, prior to making the statement, either received from a magistrate the warning provided in Article 15.17 of this code or received from the person to whom the statement is made a warning that:
(1) he has the right to remain silent and not make any statement at all and that any statement he makes may be used against him at his trial;
(2) any statement he makes may be used as evidence against him in court;
(3) he has the right to have a lawyer present to advise him prior to and during any questioning;
(4) if he is unable to employ a lawyer, he has the right to have a lawyer appointed to advise him prior to and during any questioning; and
(5) he has the right to terminate the interview at any time; and
(b) the accused, prior to and during the making of the statement, knowingly, intelligently and voluntarily waived the rights *386set out in the warning prescribed by Subsection (a) of this section.
(Emphasis added.)
Appellant’s voluntary written statement was admitted as State’s exhibit 3. At the top of each page appears the warnings required by § 2(a); the warnings mirror the statutory language almost identically except that it states any statement he makes will (instead of “may”) be used against him at trial. On each page, in boxes provided, the initials GG appear next to each part of the warnings. Finally, at the bottom of each page, in close proximity to appellant’s signature, appears additional language.
Appellant contends, in effect, the written statement is not admissible because it does not meet the requirements of article 38.22, § 2(b). Alternatively, appellant contends the written statement is inadmissible because he was under hypnosis or was intoxicated or was induced to confess by promises of leniency made by the officer who took his statement.
Clearly, the written statement contains the warnings required by Article 38.22, § 2(a). This Court, however, has never ruled what additional language, if any, is required to be included as part of a written statement in order to comply with Article 38.22, § 2(b). Unlike § 2(a), § 2(b) does not provide any guidelines as to language which might be included as part of a written statement that would constitute a knowing, intelligent and voluntary waiver by the individual of his § 2(a) rights.
In Boykin v. State, 818 S.W.2d 782 (Tex.Cr.App.1991), we held, “When we interpret statutes such as Art. 4476-15(b), Sec. 2(a)(1) we seek to effectuate the ‘collective’ intent or purpose of the legislators who enacted the legislation.... Thus, if the meaning of the statutory text, when read using the established canons of construction relating to such text, should have been plain to the legislators who voted on it, we ordinarily give effect to that plain meaning.... where application of a statute’s plain language would lead to absurd consequences that the Legislature could not possibly have intended, we should not apply the language literally.” Boykin, at 785, citing Camacho v. State, 765 S.W.2d 431 (Tex.Cr.App.1989); Smith v. State, 789 S.W.2d 590, 592 (Tex.Cr.App.1990) and Faulk v. State, 608 S.W.2d 625, 630 (Tex.Cr.App.1980).
Boykin compels us, in the present case, to determine if the written statement complies with the Legislature’s intent expressed in § 2(b): did appellant knowingly, intelligently, and voluntarily waive his § 2(a) rights?
First, appellant initialed, in the appropriate spaces on each page (a total of fifteen times) that he was informed as to his rights and it can be inferred that he understood each of his rights, the rights provided him under § 2(a). Second, appellant signed each page, his signature being adjacent to additional language which reinforces the inescapable conclusion that he knew and understood his § 2(a) rights. Third, prior to the making of his statement, appellant was informed as to his rights under Miranda v. Arizona, 384 U.S. 436, 86 S.Ct. 1602, 16 L.Ed.2d 694 (1966).
It is beyond dispute appellant received his Section 2(a) warnings, they being placed at the top of each page of his statement. The appearance of his initials before each of the five warnings is evidence that he received them and that he read and understood them; appellant does not contend otherwise. The additional language appearing next to appellant’s signature is evidence of reiteration that he understood his rights and knew what he was doing when he gave his statement. Furthermore, the additional language clearly is evidence of knowing, voluntary and intelligent waiver of his right to consult counsel before or during the giving of his statement (Sections 2(a)(3) and 2(a)(4)) and of his right to terminate the giving of his statement at any time (Section 2(a)(5)). Finally, the individual initialing of the paragraphs by appellant pertaining to his right to remain silent and to the likelihood that any statement he made would be used against him in court, when taken into context with the language at the bottom of each page next to his signature, is evidence that he knowingly, voluntarily and intelligently waived the protections afforded appellant by Sections 2(a)(1) and 2(a)(2).
*387We agree that appellant’s statement, while sufficient to comply with Article 38.22, Section 2(b), is by no means a model of clarity on this point. The clearly preferable practice is for a written statement, to meet unambiguously the requirements of Section 2(b), to contain the following language, near or adjacent to the signature of the individual giving the statement: “I knowingly, voluntarily and intelligently waived the rights described above before and during the making of this statement.” See Penry v. State, 691 S.W.2d 636 (Tex.Crim.App.1985) and Cannon v. State, 691 S.W.2d 664, 674 (Tex.Crim.App.1985). We are persuaded, however, that, though a close call, appellant did, on the face of his voluntary statement, knowingly, voluntarily and intelligently waive his Section 2(a) rights in a manner sufficient to comply with the legislature’s intent when it enacted Section 2(b).
The trial judge, following a hearing on appellant’s motion to suppress the written confession, concluded, in his findings of fact and conclusions of law, appellant evidenced his understanding of his rights and waiver thereof on the face of the statement by placing his initials by each of the warnings that appear on the face of his written confession. The court accordingly found appellant waived his rights under § 2(a). The court also found he orally waived his rights after being informed of his rights under Miranda, supra, and prior to giving his written statement.
We have held that factual determinations made by the trial court at a hearing on a motion to suppress evidence shall not be disturbed on appeal if those findings are supported by the record. Urbano v. State, 837 S.W.2d 114 (Tex.Cr.App.1992); Johnson v. State, 803 S.W.2d 272 (Tex.CrApp.1990). See also Calloway v. State, 743 S.W.2d 645 (Tex.Cr.App.1988). We find no abuse of discretion by the trial court. Appellant makes the same arguments with respect to appellant’s confession to the murder of Gregory Martin (admitted at punishment); we find them unpersuasive for the reasons given above. Points of error numbers forty-two and forty-three are overruled.
Appellant avers his confession was not voluntarily made because he was intoxicated or under hypnosis. The record does not support his claim he was intoxicated at the time he confessed. Furthermore, even if appellant was intoxicated at the time he confessed, this fact alone is not, in and of itself, sufficient to render his confession involuntary. Nichols v. State, 754 S.W.2d 185 (Tex.Cr.App.1988). At the hearing, the trial court found there was evidence appellant had been drinking prior to the time of his arrest and confession, but he was not intoxicated at the time of his arrest and confession. The court found he was not under the influence of alcohol to such an extent so as to render his confession involuntary. At a hearing to suppress evidence, the trial court is the sole judge of the weight and credibility of the evidence and the trial court’s finding may not be disturbed on appeal absent a clear abuse of discretion. Alvarado v. State, 853 S.W.2d 17, 23 (Tex.Cr.App.1993). Appellant never testified he was intoxicated when he confessed; the only evidence produced in support of appellant’s assertion is a medical screening form completed at the time of appellant’s arrest that he appeared to be under the influence of alcohol or drugs. Detective Wilson testified appellant did not appear to be intoxicated. Accordingly, the trial court did not abuse its discretion in finding appellant was not intoxicated so as to render his confession involuntary.
Appellant’s claim he was under hypnosis at the time of his confession is based on testimony by Plano Police Department Detective Meeks that Detective Wilson (the officer who took appellant’s confession) is a trained hypnotist. Appellant does not however, produce evidence or expert testimony that he was under hypnosis at the time he confessed. Detective Wilson testified he did not hypnotize appellant. Appellant fails to show any coercive conduct on the part of the police and, absent such evidence, his confession cannot be said to have been taken in such a manner so as to violate his federal due process rights. Colorado v. Connelly, 479 U.S. 157, 164, 107 S.Ct. 515, 520, 93 L.Ed.2d 473 (1986); Alvarado, supra, at 19. The trial court did not abuse its discretion in conelud-*388mg appellant was not hypnotized at the time he gave his confession.
Appellant also alleges his statement was involuntary as he was improperly induced to confess by promises of leniency made by the police. A promise made by a law enforcement officer may render a confession involuntary if it was positive, made or sanctioned by someone with apparent authority, was of some benefit to the defendant and was of such a character as would likely cause a person to speak untruthfully. Freeman v. State, 723 S.W.2d 727 (Tex.Cr.App.1986); Jacobs v. State, 787 S.W.2d 397 (Tex.Cr.App.1990). To determine if the promise of a benefit was likely to influence appellant to speak untruthfully, an appellate court must look to whether the circumstances of the promise made the defendant “inclined to admit a crime he didn’t commit.” Sossamm v. State, 816 S.W.2d 340, 345 (Tex.Cr.App.1991).
During the hearing on the admissibility of appellant’s confession, Detective Wilson testified as to his conversations with appellant.
Q. [Appellant’s Counsel] Is it a fair characterization that you told him that while you can’t make any promises, that if it’s like he’s telling it, that he didn’t pull the trigger, that Chris shot the clerk, that there’s a possibility that he wouldn’t be charged with capital murder, but he would be tried for aggravated robbery?
A. [Detective Wilson] That’s what I said.
(Vol. 12, p. 993.)
Q. What did you say?
A. I told him that if he knew anything about Chris [Vargas] any robberies, shootings and he talked to me about it, I’d do whatever I could to help him out.
(Vol. 12, p. 1011.)
[[Image here]]
Q. Did you tell him you’d talk to the D.A. and see what you could work out?
A. I told him I’d talk to the D.A.
(Vol. 12, p. 1011.) The videotape of the interview shows Detective Wilson, at least four times, said he would do what he could to help appellant if he gave information of Vargas’ involvement in other crimes.
In Dykes v. State, 657 S.W.2d 796 (Tex.Cr.App.1983) we held that, where a police officer made a general statement he would help appellant if appellant cooperated with him, appellant’s confession was voluntary and not the result of a promise of leniency or a lighter sentence. In Sorola v. State, 674 S.W.2d 809 (Tex.App. — San Antonio 1984) the court held the mere fact that the police officer told appellant he would inform the district attorney as to his cooperation or lack of same was not a promise so as to render appellant’s confession inadmissible.
Detective Wilson did not promise appellant he would not be charged with capital murder if Chris Vargas, not appellant pulled the trigger, only that it was a possibility. Detective Wilson did not make any specific promises — only that he would try to “help him out” or would “talk to the D.A.” — if appellant furnished him information on Vargas’ involvement in other crimes.
The trial court found Detective Wilson’s statements were not made in the course of plea negotiations with appellant; nor was he promised anything or tricked into confessing against his will. The court found that Detective Wilson’s comments and questions were aimed at getting appellant to tell the truth. The record supports the trial court’s finding, and appellant fails to show any abuse of discretion. Factual determinations by the trial court made at a hearing on a motion to suppress evidence should not be disturbed on appeal if supported by the record. Alvarado, supra; Johnson, supra.
Finally, appellant fails to brief separately his contentions that he is entitled to relief under both the Texas and the United States constitutions. Any point of error contending a violation of the Texas Constitution and not separately setting forth supporting arguments and authorities is inadequately briefed and will not be addressed. McCambridge v. State, 712 S.W.2d 499 (Tex.Cr.App.1986); Dinkins v. State, 894 S.W.2d 330, 350 *389(Tex.Cr.App.1995); Goodwin v. State, 799 S.W.2d 719, 723-725 (Tex.Cr.App.1990).3
Appellant’s points of error numbers forty-four through fifty-one are overruled.
Appellant’s Remaining Points of Error
In points of error numbers one through four, appellant contends the trial court erred in sustaining the State’s challenge for cause of venireperson Robert Phillips. During voir dire, Phillips expressed difficulty in answering the special issues affirmatively so as to subject appellant to the death penalty due to appellant’s youth. Appellant was eighteen years old when the offense was committed.
Q. [Prosecutor] No, I understand. I understand. It’s an option. What I am saying is in the case of a youthful defendant in a robbery-murder, you will never answer those questions in a way that will lead to the imposition of the death sentence. Is that correct?
A. [Phillips] Not the fourth one.
Q. Fourth special issue, though, is always going to be yes in the case of a youthful defendant regardless of the facts?
A. That’s right.
Q. And I’m not quarreling with you, but are you essentially telling me that if you’re on this jury I don’t have a shot at the death penalty?
A. That’s correct.
Under Texas Code of Criminal Procedure, art. 35.16(b)(3), a challenge for cause may be made by the State for the following reason: “(3) that [the juror] has a bias or prejudice against any phase of the law upon which the State is entitled to rely for conviction or punishment.”
In Hawkins v. State, 660 S.W.2d 65 (Tex.Cr.App.1983), we held that the trial court properly sustained the State’s challenge for cause to a venireperson who testified she would vote in such a manner so as to avoid the death penalty for the defendant regardless of the evidence which might be developed at trial. See also Staley v. State, 887 S.W.2d 885, 894 (Tex.Cr.App.1994); Riley v. State, 889 S.W.2d 290, 301 (Tex.Cr.App.1993); Morgan v. Illinois, 504 U.S. 719, 112 S.Ct. 2222, 119 L.Ed.2d 492 (1992). In White v. State, 779 S.W.2d 809 (Tex.Cr.App.1989) we found the trial court ruled correctly in sustaining the State’s challenge for cause to a venireperson who could vote for the death penalty only for “premeditated” murders and to another venireperson who could not consider the entire range of punishment of the offense.
We have held on several occasions that, “on appeal, we recognize that great deference must be given to the trial court judge who is in the best position to see and hear the prospective jurors and to evaluate their responses. We will reverse a trial court’s ruling on these issues only when the record shows a clear abuse of discretion on the trial court’s part.” Jacobs v. State, 787 S.W.2d 397, 402 (Tex.Cr.App.1990). See also Collins v. State, 780 S.W.2d 176, 194 (Tex.Cr.App.1986); Cantu v. State, 842 S.W.2d 667, 683 (Tex.Cr.App.1992); Butler v. State, 872 S.W.2d 227, 235 (Tex.Cr.App.1994); White, supra, at 822.
The record shows venireperson Phillips testified he would never vote so as to impose the death penalty and therefore was properly subject to a challenge for cause by the State under Article 35.16(b)(3). A prospective juror who is unable to consider the full range of punishment may be challenged for cause under the standards established by Wainwright v. Witt, 469 U.S. 412,105 S.Ct. 844, 83 L.Ed.2d 841 (1985), and Morgan v. Illinois, supra. See also Martinez v. State, 588 S.W.2d 954 (Tex.Cr.App.1979); Fearance v. State, 771 S.W.2d 486 (Tex.Cr.App.1988). Appellant fails to show any abuse of discretion by the trial court. Points of errors numbers one through four are overruled.
In points of error numbers five through seven, appellant claims the trial court erred in granting the State’s challenge for cause to venireperson Kieke and denied appellant ef-*390feetive assistance of counsel under the Sixth Amendment of the U.S. Constitution and Art. I § 10 of the Texas Constitution by denying him the opportunity to voir dire Kieke.
During the voir dire of venireper-son Kieke, the State made four challenges for cause, three of which were overruled by the trial court. The State then asked Kieke a hypothetical question with respect to special issue three (provocation). The question was allowed over the objection of appellant. Kieke answered the question in the negative, essentially stating she could never find that the killing of a robbery victim by the robber was a reasonable reaction to something the victim might have done to provoke him. Kieke did not alter her response despite appellant’s attempts to rehabilitate her on this issue. The trial court then sustained the State’s challenge for cause.
We have held on several occasions that Art. 35.16(b)(3) allows the State to challenge for cause a venireperson who indicates he or she is biased against the defendant. White, supra; Flores v. State, 871 S.W.2d 714, 719 (Tex.Cr.App.1993); Guerra v. State, 771 S.W.2d 453, 467 (Tex.Cr.App.1988). Kieke’s response clearly indicated that she could not find a murder committed during a robbery to be reasonable as a response to provocation, thus indicating a bias against appellant with respect to special issue three. The record supports the ruling of the trial court and appellant fails to show any abuse of discretion. See Jacobs, supra, at 402. Indeed, the entire record of voir dire of Kieke — some four hour’s worth — shows a vacillating veni-reperson and we will accord great deference to the decision of the trial court in such circumstances. Mooney v. State, 817 S.W.2d 693 (Tex.Cr.App.1991).
Appellant fails to cite any authorities or make any substantive arguments with respect to either his federal or Texas constitutional claims of denial of effective assistance of counsel resulting from the trial court’s action concerning venireperson Kieke. Based on McCambridge, supra, Dinkins, supra, and Texas Rule of Appellate Procedure 74(f), we overrule these claims as inadequately briefed.
Points of error numbers five, six and seven are overruled.
Appellant avers in point of error number eight that the trial court erred in granting the State’s challenge for cause to venireperson Collins. Venireperson Collins stated in his jury questionnaire he did not believe in the death penalty. In response to questions from both the State and appellant’s counsel, Collins testified he would answer the special issues in such a way as to avoid imposition of the death penalty.
Collins was properly subject to the State’s challenge for cause not because of his views on capital punishment but because he clearly stated he would answer the special issues so as to prevent its imposition. Wainwright v. Witt, supra; Staley, supra; Holland v. State, 761 S.W.2d 307 (Tex.Cr.App.1988); Smith v. State, 744 S.W.2d 86 (Tex.Cr.App.1987). Finding no abuse of discretion by the trial court, we overrule appellant’s point of error number eight.
In point of error number nine, appellant contends the trial court erred in excusing for cause venireperson Gallo. The record indicates Gallo opposed the death penalty and testified his past experiences as an army general and combat veteran would prevent him from being a fair and impartial juror.
Gallo indicated he could return a verdict of guilty “if they prove beyond a reasonable doubt, there ain’t no doubt in your mind that appellant committed the crime.” During voir dire, Gallo initially testified he could not answer the first three special issues in such a way as to result in imposition of the death penalty. Later, he indicated he could answer the special issues based on the facts. However, in response to a question asked by the court, Gallo stated he would answer special issue three in the affirmative as he would always find there to be sufficient mitigating evidence. Whereupon, the court granted the State’s challenge for cause.
The record supports the trial judge’s finding that Gallo, due to his views on the death penalty, would be unable to follow the law with respect to the special issues. We have held that a trial court’s ruling on such mat*391ters should be reversed only when the record shows a clear abuse of discretion. Jacobs, supra, at 402; Davis v. State, 782 S.W.2d 211, 216 (Tex.Cr.App.1989); Briddle v. State, 742 S.W.2d 379 (Tex.Cr.App.1987), cert. denied 488 U.S. 986,109 S.Ct. 643, 102 L.Ed.2d 573 (1987). See also Wainwright v. Witt, supra; Holland, supra; Staley, supra. When viewed in its entirety Gallo’s testimony is sufficient to support the trial court’s decision to grant the State’s challenge for cause. Point of error number nine is overruled.
Appellant avers, in point of error number ten, the trial court improperly excused for cause venireperson Wycoff. Wy-eoff testified that, due to his religious or personal beliefs against the death penally, he could not answer the special issues in such a way so as to allow imposition of the death penalty. He testified that he would always answer special issue three in the affirmative unless appellant testified he committed the murder or unless at least two eyewitnesses testified appellant committed the murder.
We previously held, in White, supra, the trial court properly sustained the State’s challenge for cause of a prospective juror who stated she could not convict the defendant of capital murder absent eyewitness testimony. See also Caldwell v. State, 818 S.W.2d 790, 791, 792 (Tex.Cr.App.1991) and Barnard v. State, 730 S.W.2d 703 (Tex.Cr.App.1987). As our holding in White is clearly on point and appellant does not present compelling reasons for us to repudiate White, appellant’s point of error number ten is overruled.
In point of error number eleven, appellant contends the trial court improperly conducted a general voir dire of fifteen prospective jurors separate and apart from the entire venire panel, on August 7, 1991. Appellant claims that this action by the trial court violated Texas Code of Criminal Procedure art. 35.17(2) and also resulted in appellant’s effectively being denied his right to request a shuffle of the jury.
The record clearly shows that no voir dire actually occurred and the fifteen prospective jurors who were present had simply indicated previously they would not be able to attend the general voir dire on August 12, 1991. No questions concerning the ease, burden of proof, reasonable doubt, etc., were addressed to the prospective jurors by the court, the State or appellant. No questions were asked to determine why the fifteen could not be present at general voir dire. One of the fifteen actually served on the jury.
As no voir dire as that term is contemplated under art. 35.17(2) actually took place on August 7, 1991 and appellant fails to show that he was harmed in any way by what did take place, appellant’s right to a shuffle under Texas Code of Criminal Procedure, art. 35.11 was not violated. Finally, the trial court did not err in failing to issue writs of attachment. Jackson v. State, 745 S.W.2d 4 (Tex.Cr.App.1988); Porter v. State, 623 S.W.2d 374 (Tex.Cr.App.1981).
Appellant’s point of error number eleven is overruled.
In points of error numbers twelve, thirteen and fourteen, appellant contends the trial court erred by conducting voir dire of small groups of venirepersons following the general voir dire of the entire panel and prior to individual voir dire. Appellant contends this action violated his due process rights under both the United States and Texas Constitutions.
Article 35.17(2) of the Texas Code of Criminal Procedure provides: “In a capital case in which the State seeks the death penalty ... on demand of the State or defendant, either is entitled to examine each juror on voir dire individually and apart from the entire panel, and may further question the juror on the principles propounded by the court.”
The record shows that, following general voir dire of the entire panel on August 12, 1991 the trial court commenced individual voir dire on September 9,1991. Initially, the court conducted voir dire in groups of eight venirepersons, following which it conducted one-on-one individual voir dire. Appellant’s objection to this procedure was overruled.
Appellant fails to cite any authority to support his position that the trial court’s action with respect to use of an intermediate and additional step in the voir dire process constitutes reversible error. This court has, *392on at least two occasions, upheld the use of sub-panels prior to one-on-one individual voir dire. Esquivel v. State, 595 S.W.2d 516 (Tex.Cr.App.1980); Hall v. State, 661 S.W.2d 113 (Tex.Cr.App.1983). Furthermore, appellant fails to make any substantive arguments or cite any authority with respect to his claims that the trial court’s action violated his federal or state constitutional due process rights and thus these points are' inadequately briefed. McCambridge, supra; Dinkins, supra; Goodwin, supra.
Appellant’s points of error numbers twelve, thirteen and fourteen are overruled.
Appellant, in points of error numbers fifteen through twenty-one, contends that numerous errors were made in the selection of the venire panel.
In point of error number fifteen, appellant alleges he was denied a special venire. A review of the record indicates that no motion for a special venire was ever filed by appellant as required by Texas Code of Criminal Procedure art. 34.01. The record does indicate appellant was provided a copy of the list of venirepersons at least two days before the date on which his ease was set for trial, per art. 34.04. Point of error number fifteen is overruled.
In points of error numbers sixteen and seventeen, appellant contends the trial court erred during his challenge to the first array and his motion to quash the first array. A challenge to the array must be in writing and supported by affidavit, as provided under Texas Code of Criminal Procedure art. 35.07. Appellant’s challenge to the first array and his motion to quash the array are both in writing, but neither are sworn to. An instrument that is not sworn to is not supported by affidavit. See Esquivel, supra; Tex.Penal Code 1.07(35). As neither of appellant’s motions are supported by affidavit, nothing is preserved for review. Hurd v. State, 513 S.W.2d 936 (Tex.Cr.App.1974); Esquivel, supra. Points of error numbers sixteen and seventeen are overruled.
Appellant, in points of error numbers eighteen through twenty-one, contends that the juror selection method employed by Collin County resulted, in effect, in a jury that did not reflect a fair cross-section of the community and tended to exclude certain racial groups. The record indicates that Collin County does not use the jury wheel method, nor are venirepersons summoned by the sheriff, the two methods described in Texas Code of Criminal Procedure art. 34.02. Collin County selects jurors utilizing a computer method based on voter registration lists, a method previously approved by the Secretary of State.
Appellant fails to produce any evidence that the juror selection method used by Collin County systematically and arbitrarily excludes a cognizable protected class, e.g., Hispanics, from jury service. He fails to show anyone was either included or excluded from jury service due to race. Appellant fails to cite any authority for his position that Collin County’s juror selection method is unconstitutional because it fails to take race into account. It is well-settled that selection of jurors from voter registration lists is constitutional under both the U.S. and Texas Constitutions. U.S. v. Carter, 568 F.2d 453 (5th Cir.1978); DeBlanc v. State, 799 S.W.2d 701, 708 (Tex.Cr.App.1990).
Furthermore, the burden of proof is on appellant to show the Collin County juror selection process intentionally, systematically and arbitrarily excludes protected classes from juty service. Appellant fails to produce any statistical or other evidence in support of his contentions.
We overrule appellant’s points of error numbers eighteen through twenty-one.
In point of error number twenty-two, appellant contends the indictment in this case should have been quashed because the grand jury was impaneled in a manner which violates Texas Code of Criminal Procedure arts. 19.01, 19.04, 19.06 and 19.09. In point of error number twenty-three, appellant alleges the grand jurors were selected in a racially discriminatory manner in violation of the Fourteenth Amendment to the U.S. Constitution.
The trial court entered findings of fact and conclusions of law. The court found that the 219th Judicial District Court *393of Collin County appointed five persons as grand jury commissioners for the January 1991 Term (no more than five commissioners may be appointed pursuant to art. 19.01(a)), and there was no evidence that they were not qualified under art. 19.01(a) to serve. The court found no evidence that the twenty persons selected as grand jurors were not qualified to serve as such under art. 19.08. The court found no evidence of racial discrimination with respect to selection of the grand jurors.
We have held that, absent an allegation of fraud or injury resulting from the selection of the grand jurors, minor deviations from the statutory procedure do not rise to a level requiring reversal. Gentry v. State, 770 S.W.2d 780 (Tex.Cr.App.1988); Martinez v. State, 134 Tex.Crim. 180, 114 S.W.2d 874 (App.1938); Ex parte Becker, 459 S.W.2d 442 (Tex.Cr.App.1970). Appellant does not allege any fraud in the process used to select grand jurors nor does he show that the manner in which the grand jury was selected was injurious to his rights. Appellant fails to support, with evidence, his assertion that there were six grand jury commissioners in violation of the statutory maximum of five.
As a general rule the findings of the trial court in a pretrial hearing are not disturbed on appeal absent a showing by appellant that the trial court abused its discretion. Lucas v. State, 791 S.W.2d 35 (Tex.Cr.App.1989); Russell v. State, 727 S.W.2d 573 (Tex.Cr.App.1987); Hawkins v. State, 613 S.W.2d 720 (Tex.Cr.App.1981). Appellant has shown no abuse of discretion by the trial court and fails to show any harm resulting from his allegations of various minor statutory violations with respect to the selection of the grand jury. Point of error number twenty-two is overruled.
Appellant correctly asserts that it is a violation of the U.S. Constitution’s equal protection clause for the State to try a defendant under an indictment issued by a grand jury from which persons of his race or color have been excluded by the State. Hernandez v. Texas, 347 U.S. 475, 74 S.Ct. 667, 98 L.Ed. 866 (1954); Muniz v. State, 672 S.W.2d 804 (Tex.Cr.App.1984).
The United States Supreme Court, in Castaneda v. Partida, 430 U.S. 482, 97 S.Ct. 1272, 51 L.Ed.2d 498 (1977) established a three-part test for determining if an equal protection violation has occurred in the selection of a grand jury. The burden rests on the defendant, the Court held, to ... “(2) demonstrate the group is underrepresented by comparing the proportion of the group in the total population to the proportion called to serve over a significant period of time.” Castaneda, at 494, 97 S.Ct. at 1280.
Appellant failed to present any evidence of the percentage of Hispanics in Collin County. He offered no evidence as to the racial composition of the grand jury that indicted him, except that two of the twenty grand jurors were white. Furthermore, he has failed to produce evidence of any disparity between the percentage of residents of Collin County that are Hispanic and the percentage of residents summoned for service as grand jurors in Collin County that are Hispanic. Appellant fails to satisfy the second part of the test set forth in Castaneda. We overrule appellant’s point of error number twenty-three.
In point of error number twenty-four, appellant contends he was denied his right under art. 33.03 to be present at certain proceedings held on August 21, 1991. On that day about ten prospective jurors were qualified and received instructions from the court. Counsel for appellant was notified in advance but he informed the court he could not be in attendance because of some unspecified medical reason and because he would be in trial. Appellant and appellant’s counsel indicated they had no objection to the proceedings occurring without their presence and so indicated on the record. Subsequently, the State filed a motion to quash the venire. At the hearing on the motion, appellant indicated his objection to it. The trial court complied with appellant’s wishes and denied the state’s motion.
We have held that a defendant may not, by his own actions, create reversible error. Appellant, in the present case, affirmatively waived his right to be present at the August 21 proceedings, a confrontation clause-based *394right granted under Texas Code of Criminal Procedure 33.03. We have held that this right, even if denied, is subject to harmless error analysis. McMahon v. State, 582 S.W.2d 786 (Tex.Cr.App.1978), cert. denied 444 U.S. 919, 100 S.Ct. 238, 62 L.Ed.2d 175 (1978). See also Weber v. State, 829 S.W.2d 394, 396 (Tex.App. — Beaumont 1992). Appellant was not denied his right to be present — he waived it. Furthermore, he objected to the State’s motion to quash the venire, the only method by which the effects of the August 21 proceedings could have been eliminated. Our holdings in Curtis v. State, 519 S.W.2d 883 (Tex.Cr.App.1975), Beasley v. State, 634 S.W.2d 320 (Tex.Cr.App.1982) and Kelley v. State, 823 S.W.2d 300 (Tex.Cr.App.1992) are dispositive.
Appellant’s point of error number twenty-four is overruled.
In points of error numbers twenty-five through thirty, and points of error numbers thirty-one through thirty-six, appellant avers that the State’s peremptory challenges to venirepersons Holmes, an African-American, and Diaz, a Hispanic, were exercised in a racially discriminatory manner. As a result, appellant alleges he was denied due process of law under both the Texas and United States Constitutions and the right to a fair and impartial jury under both the United States and Texas Constitutions. Furthermore, appellant claims he was subjected to cruel and unusual punishment in that the death penalty was imposed on him in an arbitrary and capricious manner in violation of both the Texas and United States Constitutions.
The United States Supreme Court has held that it is a violation of the equal protection clause of the United States Constitution for the State or for the accused to exercise peremptory challenges in a racially discriminatory manner. Batson v. Kentucky, 476 U.S. 79, 106 S.Ct. 1712, 90 L.Ed.2d 69 (1986); Powers v. Ohio, 499 U.S. 400, 111 S.Ct. 1364, 113 L.Ed.2d 411 (1991); Georgia v. McCollum, 505 U.S. 42, 112 S.Ct. 2348, 120 L.Ed.2d 33 (1992). Batson has been interpreted by the Court to proscribe peremptory challenges based on gender. J.E.B. v. Alabama ex rel. T.B., 511 U.S. 127, 114 S.Ct. 1419, 128 L.Ed.2d 89 (1994).
Appellant does not make an equal protection claim and Batson, Powers, McCollum, and J.E.B. are equal protection cases. In any event, the record clearly demonstrates the State exercised its peremptory challenges in a racially neutral manner.
A. Prospective Juror Holmes (Points of Error Twenty-Five Through Thirty)
In her juror questionnaire, venireperson Holmes stated “I could never, under any circumstances and regardless of the facts, return a verdict which would result in the death penalty.” She affirmed her opposition to the death penalty during voir dire. She also indicated her inability to vote for conviction regardless of the evidence presented by the State. She refused to state she could answer special issue number three in the negative and indicated she would answer it in the affirmative in any event. She also claimed that her son had been unfairly prosecuted in Collin County.
The State then exercised its peremptory challenge (an earlier challenge for cause was denied by the court), giving its reasons as being her opposition to the death penalty, her inability to vote for conviction regardless of the evidence, her refusal to state she could answer, “no” to special issue number three and bias against the prosecution because of her statement her son had been unfairly prosecuted in Collin County, and deceptive answers.
The trial court found the State’s use of its peremptory challenge was not racially motivated.
“... The Court finds that the reasons for challenge or for exercising a peremptory strike with respect to Hazel Holmes are racially neutral being a — well, has previously indicated a close call with respect to challenge for cause and the Court is of the opinion and belief, based on the State’s reasons that they are legitimate and racially neutral.”
*395B. Prospective Juror Diaz
Prospective Juror Diaz expressed great reluctance to impose the death penalty on appellant because of appellant’s youth. He testified that he would hold the State to a very high burden of proof during the punishment phase of the trial. Diaz stated he would place the burden of proof as to mitigation on the State and that the burden would be “treated the same as beyond a reasonable doubt.” Finally, Diaz testified that life in prison (without parole) was an appropriate punishment for persons with a record of extreme violence.
The Court found that the State used its peremptory challenge to strike Diaz in a racially neutral manner.
“With respect to Mr. Diaz, I have listened carefully, particularly carefully, in this to this voir dire. I believe that there were ample reasons for either side to have exercised a peremptory strike in this particular instance, although he was not challenged for cause and he would otherwise be a qualified juror, but the Court is of the opinion that either side could have legitimately and from a racially neutral standpoint exercised a peremptory stride with respect to this particular juror. ...”
Q. [Prosecutor]: Judge, so the record is clear, is the Court making a finding that my explanations are racially neutral?
A. [The Court]: It is.
The record shows the State had legitimate concerns as to the impartiality of venireper-sons Diaz and Holmes. Appellant fails to show any purposeful discrimination on the part of the State. Indeed, appellant does not make a prima facie showing that the State’s peremptory challenges were racially motivated, which he is required to do. Wheatfall v. State, 882 S.W.2d 829, 835 (Tex.Cr.App.1994), cert. denied, — U.S. -, 115 S.Ct. 742, 130 L.Ed.2d 644 (1995). Each venireperson’s responses to questions posed to them during voir dire clearly demonstrate that they were not favorable to the State and that the State had very good reasons — having absolutely nothing to do with their race — for not wanting either on the jury. In exercising its peremptory challenges to Holmes and Diaz, the State was merely acting in a manner that the peremptory challenge system encourages — the selection of juries that are devoid of members who are markedly partial to either side. See Holland v. Illinois, 493 U.S. 474, 110 S.Ct. 803, 107 L.Ed.2d 905 (1990).
We have held that where the decision of the trial court with respect to peremptory challenges or challenges for cause is supported by the record and appellant fails to show an abuse of discretion, we will not reverse based on such decision. Vargas v. State, 838 S.W.2d 552 (Tex.Cr.App.1992). Cantu, supra; Caldwell, supra; White, supra. See also Whitsey v. State, 796 S.W.2d 707 (Tex.Cr.App.1989); Williams v. State, 804 S.W.2d 95, 101 (Tex.Cr.App.), cert. denied, 501 U.S. 1239, 111 S.Ct. 2875, 115 L.Ed.2d 1038 (1991). In the present case, the record supports the findings of the trial judge that there were ample, non-racial reasons to justify the State’s exercise of peremptory challenges to Diaz and Holmes; appellant fails to show any abuse of discretion on the part of the court in so finding. Furthermore, appellant fails to show the State’s racially-neutral explanations given to justify these two peremptory challenges were merely a sham or were pretextural. See Williams, supra, at 101.
Appellant’s points of error numbers twenty-five through thirty-six are overruled.4
In points of error numbers thirty-seven through forty-one, appellant contends that the very exercise of peremptory challenges by the State violates the Sixth, Eighth and Fourteenth Amendments to the U.S. Constitution as well as Article I, §§ 10,13 and 19 of the Texas Constitution and that Article 35.15, *396Texas Code of Criminal Procedure is facially unconstitutional.
Appellant argues, in effect, that neither the Texas nor the federal constitutions permit granting of peremptory challenges to the State and doing so resulted in appellant — and any other defendant — being tried by a jury biased in favor of the State. Appellant cites no authority to support his argument that peremptory challenges are unconstitutional per se under either the federal or Texas constitutions, and therefore nothing is presented for our review. Tex.Rule App. Proc. 74(f); McWherter v. State, 607 S.W.2d 531 (Tex.Cr.App.1980); McCambridge, supra; Dinkins, supra.
The validity of the peremptory challenge as a means to help ensure the selection of a fair and impartial jury has been recognized as constitutionally valid for many years. Batson, supra,; Hayes v. Missouri, 120 U.S. 68, 7 S.Ct. 350, 30 L.Ed. 578 (1887); Whitsey v. State, 796 S.W.2d 707 (Tex.Cr.App.1989). Appellant conveniently ignores the fact that Art. 35.15(a) provides both the State and the defendant, in a capital case, an equal number of peremptory challenges (fifteen).
We overrule appellant’s points of error numbers thirty-seven through forty-one.
Appellant avers, in point of error number fifty-two, the trial court erred, in its charge to the jury in the guilt/innocenee phase of the trial, in including the phrase “intent or knowledge may be inferred by acts done or words spoken.” The State was required, in order to convict appellant of capital murder, to prove beyond a reasonable doubt that the murder was committed in the course of a robbery or attempted robbery. Tex.Penal Code § 19.03(a)(2).
The trial court defined robbery in its charge to the jury thusly: “A person commits a robbery if in the course of committing theft, as defined hereinafter, and with intent to obtain or maintain control of the property, he intentionally or knowingly causes bodily injury to another.” Neither the State nor the appellant objected to this portion of the charge; nor did either object to the trial court’s definition of “knowingly.”
Appellant objected to inclusion of the phrase described above as, among other things, a comment on the evidence. Appellant’s objection was overruled. Appellant also claims that the inclusion of the phrase complained of allowed the jury to impermissi-bly find appellant intentionally committed the murder (a required element for capital murder) based on inferences as opposed to specifically finding that appellant had a conscious desire or intent to cause the death of Mr. Turski.
The facts of the offense clearly support the jury’s finding that appellant intentionally and knowingly murdered Mr. Turski in the course of committing or attempting to commit a robbery. First, he entered the station, toting a shotgun. Then, after ordering Mr. Turski to give him all the money in the cash register, he forced him into a back area and made him get down and shot him in the stomach with a shotgun blast, and after chasing him outside, appellant reloaded and shot him in the back of the head. A rational jury could find beyond a reasonable doubt from the evidence — including appellant’s videotaped and written confessions — that appellant intentionally and knowingly murdered Mr. Turski. Jackson v. Virginia, 443 U.S. 307, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979); Dunn v. State, 721 S.W.2d 325 (Tex.Cr.App.1986).
Assuming, arguendo, that it was error to include the complained-of words in the jury charge, the test for determining whether a jury charge error requires reversal is set forth in Almanza v. State, 686 S.W.2d 157 (Tex.Cr.App.1984).
“If the error in the charge was the subject of a timely objection in the trial court, then reversal is required if the error is ‘calculated to injure the rights of the defendant,’ which means no more than there must be some harm to the accused from the error.” Al-manza, at 171. “... [T]he actual degree of harm must be assayed in light of the entire jury charge, the state of the evidence, including the contested issues and weight of probative evidence, the argument of counsel and any other relevant information revealed by the record of the trial as a whole.” Alman-za, at 171.
*397No objection was made to any other portion of the jury charge given at the guilt/innocence phase. An examination of the jury charge shows the trial court properly charged the jury on the definitions of robbery, knowingly, intentionally, reasonable doubt and capital murder. (Transcript, vol. 6, pp. 1048-1059.) The evidence of appellant’s guilt — including written and videotaped confessions — is overwhelming. Accordingly, based on Almanza, we hold that any error in including the words in the jury charge at the guilVinnocence phase to which appellant objects is harmless beyond a reasonable doubt.
Appellant’s point of error number fifty-two is overruled.
Appellant avers the trial court erred in failing to include, in its charge to the jury at the punishment phase, his requested submission on provocation. Article 37.071(b)(3) provides that the trial court shall submit the issue of provocation to the jury if raised by the evidence. “In order to raise the issue of provocation, there must be evidence of the deceased’s conduct just prior to death and that evidence must be sufficient to be considered provocation.” Lucas v. State, 791 S.W.2d 35, 65 (Tex.Cr.App.1989); Hernandez v. State, 643 S.W.2d 397 (Tex.Cr.App.1982).
Appellant’s own written confession states he forced Mr. Turski onto his knees in a back room after taking all the money out of the cash register. He then “panicked” and shot the clerk (in the stomach) with the shotgun. The clerk then threw a chair at appellant and ran out of the store. Appellant chased him down and, after reloading, shot Mr. Turski in the back of the head. The medical examiner testified that both shotgun wounds were capable of causing death.
There is no evidence that, prior to being shot the first time — a mortal wound — that Mr. Turski struggled with appellant or did anything other than comply with appellant’s orders. While there is evidence — consisting of appellant’s statement — that Mr. Turski attempted to escape after being shot the first time, he had already been mortally wounded. In any event, Mr. Turski’s attempt to flee to save his life is not, given our holding in Lucas, evidence sufficient to raise the issue of provocation with respect to appellant’s subsequently shooting Mr. Turski in the back of the head after reloading his weapon.
Appellant’s fifty-third point of error is overruled.
In points of error numbers fifty-four through fifty-six, appellant contends various errors were made by the trial court in the submission of the mitigation issue to the jury. The trial court submitted the following to the jury as Special Issue Three: “Whether, taking into consideration all of the evidence, including the circumstances of the offense, the defendant’s character and background, and the personal moral culpability of the defendant, there is a sufficient mitigating circumstance or circumstances to warrant that a sentence of life imprisonment rather than a death sentence be imposed.”
The above language is that which is currently found in Article 37.071(e); this particular section was not in effect at the time of appellant’s trial. Article 37.071 in effect at that time did not require the jury be instructed to consider mitigating evidence in assessing punishment.
The Supreme Court has held that the jury must be permitted to consider mitigating evidence. Jurele v. Texas, 428 U.S. 262, 96 S.Ct. 2950, 49 L.Ed.2d 929 (1976); Eddings v. Oklahoma, 455 U.S. 104, 102 S.Ct. 869, 71 L.Ed.2d 1 (1982). Both the Supreme Court and this Court have held that where the jury was charged on the two special issues (deliberateness and future dangerousness) and the jury was specifically instructed to take into consideration, when answering those issues, all aggravating or mitigating evidence submitted during the entire trial, defendant’s Eighth and Fourteenth Amendment rights were not violated. Johnson v. Texas, 509 U.S. 350, 113 S.Ct. 2658, 125 L.Ed.2d 290 (1993); Lackey v. State, 819 S.W.2d 111 (Tex.Cr.App.1989) (not error to fail to instruct jury to consider specifically appellant’s age as a mitigating factor as the jury’s answer as to special issue two (future dangerousness) would reflect their consideration of all the mitigating evidence); Jackson v. State, 822 S.W.2d 18 (Tex.Cr.App.1990).
*398The issue, however, is whether appellant’s constitutional rights were violated by the trial court’s submission of special issue three to the jury. Article 37.071(e), as currently in effect, was enacted, at least in part, to address Penry v. Lynaugh, 492 U.S. 302, 109 S.Ct. 2934, 106 L.Ed.2d 256 (1989) in which the Court found that given the unusual facts of the case, the mitigating evidence (mental retardation, abuse victim) would likely tend to promote a “yes” answer to special issue two (future dangerousness), thus turning mitigating evidence into, in effect, aggravating evidence. In Penry, the Court found Article 37.071 to be unconstitutional as applied because it failed to instruct adequately the jmy to consider his mitigating evidence in answering the special issues.
We have held that Article 37.071 is not unconstitutional for failing to contain a provision that directs and instructs the jury’s consideration of mitigating evidence presented at the punishment phase as such evidence could be given effect by the jury through the special issues submitted to them. Gosch v. State, 829 S.W.2d 775 (Tex.Cr.App.1991). We have also held that Article 37.071 is not unconstitutional for failing to provide standards for determining sufficiency of evidence with respect to the special issues. Cantu v. State, 842 S.W.2d 667 (Tex.Cr.App.1992). In Demouchette v. State, 731 S.W.2d 75 (Tex.Cr.App.1986) we rejected appellant’s claim that Article 37.071 is unconstitutional because it does not inform the jury how to apply mitigating evidence in light of the aggravating language of the special issues.
' In answering special issue number three, the jury must consider all the evidence they have heard during trial. Appellant’s contention that the language somehow prevented the jmy from consideration of constitutionally relevant evidence as mitigating circumstances, the test he must meet under Johnson, supra, at 306, is without merit given the very words of the language about which he complains. The cases cited above do not support appellant’s claims that the state or federal constitution require the jury be instructed as to how to weigh mitigating evidence vis-a-vis aggravating evidence, or that the jury be instructed to consider only mitigation evidence when answering special issue three, or that the jmy be instructed to consider or give weight to specific kinds of evidence (e.g. appellant’s youth) as mitigating circumstances. Finally, appellant fails to cite any authority to sustain his position that inclusion of the word “sufficient” in special issue three unconstitutionally shifts the burden of proof with respect to mitigation to appellant, which appellant concedes in his brief.5
Appellant’s points of error numbers fifty-four through fifty-six are overruled.
Appellant contends, in points of error fifty-seven, fifty-eight and fifty-nine, the trial court erred in the punishment phase by denying his three special requested jury instructions. Appellant submitted three requested special jury instructions regarding mitigating evidence, i.e., appellant’s troubled family history, appellant’s drug use and appellant’s history of alcoholism. Evidence was presented at trial that appellant was physically abused by both of his stepfathers. Considerable evidence of appellant’s histories of alcohol and drug abuse was also presented.
Appellant, however, did receive a “Penry” instruction, special issue number three, which instructed the jury to consider the character and background of appellant in determining if there were sufficient mitigating circumstances to warrant imposition of a life sentence rather than a death sentence. This instruction provided a means by which the jury could consider appellant’s family history, drug use and alcoholism (and any other mitigating evidence) as mitigating circumstances. Appellant was provided more than what was required under Article 37.071 then in effect, as the language constituting special issue number three did not become part of Article 37.071 until after appellant’s trial.
We have held on several occasions that the jmy is given an opportunity to give full con*399sideration to mitigation evidence raised during the trial in its consideration of the special issues. Gunter v. State, 858 S.W.2d 430 (Tex.Cr.App.1993); Nobles v. State, 843 S.W.2d 503 (Tex.Cr.App.1992); Butler v. State, 872 S.W.2d 227 (Tex.Cr.App.1994). Appellant was accordingly not entitled to any special instructions requiring the jury to consider appellant’s drug use, alcoholism and family background as mitigating circumstances.
Appellant’s points of error numbers fifty-seven, fifty-eight and fifty-nine are overruled.
In points of error numbers sixty through sixty-five (argued collectively by appellant), appellant avers that the trial court’s refusal to permit appellant to question sixteen venirepersons as to whether they could consider certain evidence as mitigating circumstances violated appellant’s rights under both the Texas and United States Constitutions.
The trial court permitted appellant to ask venireperson Canup if the venireperson could consider youthful age to be a mitigating circumstance. Appellant then began to inquire of the venireperson as to whether or not the venireperson could consider other factual mitigating circumstances. The State objected. Appellant moved the Court to ask the venireperson the following four questions:
1. The law provides that voluntary intoxication which does not rise to the level of temporary insanity is a mitigating circumstance which a juror must consider. Can you consider voluntary intoxication which does not rise to the legal [sic] of temporary insanity a mitigating circumstance?
2. The law provides that a troubled family background is a mitigating circumstance which a juror must consider. Can you consider troubled family background as a mitigating circumstance?
3. The law provides that alcoholism or drug addiction is a mitigating circumstance which a juror must consider. Can you consider alcoholism or drug addiction as a mitigating circumstance?
4. Finally, the law provides that a good jail record is a mitigating circumstance which a juror must consider. Can you consider a good jail record as a mitigating circumstance?
The trial court denied appellant’s motion and appellant timely objected to the court’s ruling. Of the sixteen venirepersons to which appellant was denied the opportunity to ask the four questions listed above, appellant exercised peremptory challenges as to eight. Another five were excused for cause or by peremptory challenges exercised by the State. Three of the venirepersons, Kem-mett, Pridgen and Young, ultimately served on the jury. Appellant cannot show any error with respect to a venireperson who was excused from the panel. Collins v. State, 548 S.W.2d 368 (Tex.Cr.App.1976); Simon v. State, 406 S.W.2d 460 (Tex.Cr.App.1966).
His claim of error thus is limited to his being prevented from examining venireper-sons Kemmett, Young and Pridgen as to their feelings regarding evidence of a good jail record, voluntary intoxication, alcohol or drug addiction, and troubled family background as mitigating circumstances.
A trial court’s restriction on questioning of venirepersons is reviewed under an abuse of discretion standard. Caldwell, swpra; Woolridge v. State, 827 S.W.2d 900 (Tex.Cr.App.1992). Questions that would require the prospective jurors to commit themselves as to how they might resolve factual issues in the case are improper. Harkey v. State, 785 S.W.2d 876 (Tex.App.—Austin 1990).
In Coleman v. State, 881 S.W.2d 344 (Tex.Cr.App.1994), cert. denied, — U.S. -, 115 S.Ct. 763, 130 L.Ed.2d 660 (1995), a capital case, appellant sought to ask several venire-persons as to whether they could consider appellant’s troubled family history and good jail conduct as mitigating circumstances that would call for a lesser penalty. The trial court sustained the State’s objection to the question as trying to commit the juror to considering that (his troubled family history) as a mitigating circumstance. Coleman, at 350. We held that the trial court did not abuse its discretion in refusing to allow appellant to ask questions based on facts peculiar to the case on trial. “Moreover, the venireperson said she would consider all the *400evidence in answering the special issues and follow the trial court’s instructions; the law does not require a veniremember to give any specified weight to a particular piece of evidence.” Coleman, at 351. See also Allridge v. State, 762 S.W.2d 146, 163-64 (Tex.Cr.App.1988), cert. denied, 489 U.S. 1040, 109 S.Ct. 1176, 103 L.Ed.2d 238 (1988); White, supra; Cuevas v. State, 742 S.W.2d 331, 346 (Tex.Cr.App.1987), cert. denied, 485 U.S. 1015, 108 S.Ct. 1488, 99 L.Ed.2d 716 (1988).
The trial court did not abuse its discretion in denying appellant the opportunity to ask the four questions described above. Appellant did introduce evidence as to appellant’s alcohol and drug problems, his family history, his jail conduct and his voluntary intoxication at trial; he was not entitled to ask venirepersons to “commit themselves” to consider such evidence as mitigating circumstances. Furthermore, appellant fails to offer any evidence venirepersons Kemmet, Pridgen and Young were objectionable or expressed any inability or unwillingness to consider all of the evidence in answering the special issues or any inability or unwillingness to follow the trial court’s instructions. Additionally, appellant was provided opportunities to discuss appellant’s youth, troubled family history, his character and alcohol/drug use as mitigating circumstances during individual voir dire and during subpanel voir dire with respect to Kemmet. Similar opportunities were provided with respect to Pridgen and Young. Appellant, assuming arguendo that Coleman is inapplicable, has not, based on the record, shown error and we are not required to accept allegations of error not supported by the record. Beck v. State, 573 S.W.2d 786 (Tex.Cr.App.1978).
Finally, while appellant contends he is entitled to relief under both the U.S. and Texas Constitutions, appellant fails to brief separately his state and federal constitutional arguments, and fails to offer substantive arguments and analysis for each, as required by Texas Rule of Appellate Procedure 74(f) and McCambridge, supra Thus, his points of error contending a violation of the Texas Constitution are inadequately briefed and need not be addressed. Dinkins, supra; McCambridge, supra; Goodwin, supra
Points of error numbers sixty through sixty-five are overruled.
Appellant, in point of error number sixty-six, contends the trial court erred in overruling appellant’s challenge for cause to venireperson Yoast. The voir dire of veni-reperson Yoast was extensive and covered nearly 150 pages of the record. Appellant contends venireperson Yoast was unable to distinguish between “intentional” and “deliberate.” We have held that such a venireper-son, unless rehabilitated, should be excused upon challenge for cause. Martinez v. State, 763 S.W.2d 413 (Tex.Cr.App.1988); Felder v. State, 758 S.W.2d 760 (Tex.Cr.App.1988).
Venireperson Yoast initially indicated some concern about deliberate versus intentional. The State, later in voir dire, asked venireper-son Yoast the following two questions:
Q. [Prosecutor] ... I discussed with you on the general voir dire portion of this trial this idea of the difference between deliberateness and intentional. Now, I’m willing to bet that before you came into this courtroom that if anybody had asked you’d have defined the two — the difference, if any, would have been slight? Is that a fair statement?
A. [Yoast] Yes.
Q. ... We have every expectation in this trial that the term intentional conduct will, in fact, be defined for you so that will give you some starting point to proceed from. I would suggest to you that that definition is that a person who acts intentionally acts with a conscious objective or desire to cause the result. All right?
A. Okay.
Q. The key words being there, conscious objective or desire. Do you agree with me that it would be kind of pointless for the law to ask you the same question twice?
A. Yeah.
Q. Okay. Do you agree with me, then, that it certainly stands to reason that this question about deliberate conduct seems to be asking whether there is *401something more than simply intentional conduct?
A. Yes.
The record shows that venireperson Yoast understood, based on his answers to the above questions, that there is a difference between intentional and deliberate conduct. On pp. 515-516, venireperson Yoast was asked an additional question on this issue.
Q. [State] Now, I’ve talked in terms of premeditation and I gave you an example in the general voir dire about you walking out the door and you see your boss, shake his hand. You might consider that intentional. Maybe not. Whereas you see him across the room and you decide, well, I’m going to go over there and shake his hand. Okay. You might consider that deliberate as opposed to intentional. Maybe not. It seems useful to think of the deliberation in terms of choosing between options, that if a person has at least put that amount of thought into it, if that amounts to a choice between various options, then it would seem fair to suggest that that displays or demonstrates [a] certain type of deliberation.
For example, if you’ve got just maybe a murder, somebody walks into the store, points a gun at you, give me your money, bam, walks out. You might consider that intentional; you might consider that deliberate. I don’t know. But that’s one fact scenario that you could potentially be confronted with.
You can change that a little bit and show, walk into the store, give me the money. I get the money and I step — and then put that muzzle right between your eyes and blow you away. You might consider, well, you know, we’ve gone a little beyond intentional here. This seems to be conduct that would — deliberately cause the death of the deceased, was committed deliberately and with a reasonable expectation that death would result.
It could be that sort of thing, and again, you don’t have to give us examples. You just need to be able to understand what this concept is and deal with it. Has that been helpful in the least? Do you have questions?
A. Yes. I feel it has. Thank you.
Appellant asked venireperson Yoast several questions concerning intentional and deliberate.
Q. [Appellant] Okay. Now, in that case where you have premeditation or what we’ve been calling premeditation, I mean, I, I think what you did in Mr. Blake’s example was use some of that premeditation to come up with what you called deliberateness. Isn’t that true?
A. Possible.
Q. But if you take out that premeditation, there’s just not any difference?
A. Apparently, yes.
Q. You agree with that?
A. Yes.
Appellant, after his challenge for cause to venireperson Yoast was denied, exercised his final (fifteenth) peremptory challenge and Yoast was excused.
We have held that the trial court’s rulings with respect to a challenge to a venireperson must be reviewed in light of all of the answers given by the venireperson during voir dire. Mooney v. State, supra. We have also held that the question of whether a challenge for cause was wrongfully denied by the trial court is subject to an abuse of discretion standard. Garcia v. State, 887 S.W.2d 846 (Tex.Cr.App.1994); Wheatfall, supra.
In response to the State’s voir dire questions, venireperson Yoast clearly indicated he understood “intentional” and “deliberate” were not one and the same and that the State’s burden of proof on “deliberateness” went beyond its burden of proof on intent. Venireperson Yoast’s responses to appellant’s voir dire questions were vacillating and unclear due, perhaps in part to the confusing nature of the questions themselves. When faced with a vacillating or confused venire-person, we accord great deference to the trial judge because he — unlike us — was afforded the opportunity to observe the venireperson and to listen to his answers. Garcia, supra; Satterwhite v. State, 858 S.W.2d 412 (Tex.Cr.App.1993), cert. denied, — U.S. -, 114 *402S.Ct. 455, 126 L.Ed.2d 387 (1993); Perillo v. State, 758 S.W.2d 567 (Tex.Cr.App.1988):
The record, when taken as a whole, does not show the trial judge abused his discretion in his denial of appellant’s challenge for cause to venireperson Yoast. Appellant’s sixty-sixth point of error is overruled.
In point of error number sixty-seven, appellant avers the trial court erred in permitting the state to conduct an in-court identification of Vargas, in the presence of the jury. During the State’s ease-in-ehief, it called Shawn Robinson as a witness and' proposed to have him identify Vargas in the jury’s presence, over appellant’s objection, which was overruled. Vargas was brought into the courtroom in shackles, dressed in jail clothes, and guarded by two Collin County deputy sheriffs.
In appellant’s objection, he alleged the in-court identification of Vargas was prejudicial, irrelevant and unnecessary. However, appellant himself mentioned Vargas was present when he was arrested, thereby making his identification relevant and admissible under Texas Rules of Criminal Evidence 401 and 402.
Furthermore, appellant fails to cite any authority supporting his contention that the error, if any, is reversible error. Therefore, nothing is preserved for our review. McCambridge, supra; Overton v. State, 490 S.W.2d 556 (Tex.Cr.App.1973).
Point of error number sixty-seven is overruled.
The judgment of the trial court is affirmed.
McCORMICK, P.J., and WHITE, J., join, except as to the disposition of point of error 42.
CLINTON, J., dissents.
. Appellant was indicted for the capital murder of Craig Turski.
. All references to the various sections of the Texas Code of Criminal Procedure and the Texas Penal Code are to those in effect as of the date of the offense.
. We note that appellant's contentions that Article 1, § 10 of the Texas Constitution affords him greater protection against self-incrimination and of his right to counsel than the Fifth and Sixth Amendments to the U.S. Constitution have no merit. Thomas v. State, 723 S.W.2d 696 (Tex.Cr.App.1986).
. The United States Supreme Court’s decision in Purkett v. Elem, - U.S. -, 115 S.Ct. 1769, 131 L.Ed.2d 834 (1995), although issued after the State and appellant filed their briefs in the present case, is squarely on point and does not change our disposition of these points of error. Appellant does not make any argument or cite any authority to support his position that a different result would be indicated under Article I, §§ 10, 13 or 19 of the Texas Constitution, and thus his state constitution-based claims are inadequately briefed and need not be addressed. McCambridge, supra; Dinkins, supra; Tex.R.App. Proc. 74(f).
. It should be noted the trial court did instruct the jmy that appellant's youthful age is a mitigating circumstance.
