OPINION
PAGE, Justice.Appellant Samuel Lee Byers (“Byers”) was indicted for first-degree murder by a Hennepin County Grand Jury for the shooting death of Roy Griffin, Sr. (“Griffin”). After a jury trial, Byers was acquitted of first-degree murder, but was convicted of second-degree felony murder in violation of Minn. Stat. §§ 609.19(2), 609.11, and 609.05 (1996) and sentenced to 240 months in prison. Byers appealed, and the court of appeals affirmed, concluding that although the trial court erred in admitting a co-defendant’s out-of-court statement,1 the error was harmless beyond a reasonable doubt.
On appeal, Byers contends that admission of the out-of-court statement from the co-defendant, who was unavailable to testify at his trial, constituted inadmissible hearsay and violated his right to confrontation under the Sixth Amendment to the United States Constitution. Byers further contends that because admission of the co-defendant’s out-of-court statement was not harmless beyond a reasonable doubt, he is entitled to a new trial. While we agree with the result reached by the court of appeals, we conclude that the court of appeals erred in its analysis. Therefore, we affirm on other grounds.
The record from Byers’ trial indicates that Griffin was shot and killed during a robbery of his apartment located at 2701 15th Avenue South in Minneapolis. Griffin shared the apartment with his girlfriend, Denise Berry (“Berry”), and his six-year-old son Roy Griffin, Jr. (“Griffin Jr.”). At approximately 5:30 p.m. on March 31, 1995, two men, one of them allegedly Byers, knocked on the front door of Griffin’s apartment. Present in the apartment at that time were Griffin, Berry, Griffin Jr., and Griffin’s cousin, Christopher *490Minor (“Minor”). The two men were let in to the apartment and spoke with Griffin about buying marijuana. Shortly after the two men were let in, there was another knock on the door. The man alleged to be Byers answered the door, and two additional men entered the apartment. As they did so, all four men who had entered the apartment brandished handguns. The men, two wearing baseball caps2 and two wearing knit caps, ransacked the apartment, demanded to know where Griffin’s drugs were located, and instructed Griffin, Berry, Minor, and Griffin Jr. not to “try anything funny.” Griffin was held at gunpoint by one of the robbers on the floor of his bedroom. Griffin Jr. was also held in that bedroom. Berry and Minor were held at gunpoint in the apartment’s living .room, face down on the floor. As Griffin was being held on the floor, he attempted to get up and was hit in the head with a gun. When he attempted to get up a second time, he was shot point blank in the left temple. The four men involved in the robbery then fled the apartment, left the building, and ran into the alley behind Griffin’s apartment building. That alley runs north and south between Bloomington Avenue and 15th Avenue South.
Joanna Amos (“Amos”) testified that, on the afternoon of Griffin’s murder, as she and a friend were walking home from the grocery store, she observed four young men running south down the alley towards 28th Street East. When the young men reached 28th Street East, two of them turned east on 28th Street East and two crossed 28th Street East, continued down the alley, and turned at a building on the north end of the block. The four young men were wearing dark, baggy, oversized clothes. Two of the young men Amos observed were wearing knit caps, and one was carrying a large purse. Amos was otherwise unable to identify any of the young men. Following up on a tip to check the garbage cans between Bloomington Avenue and 15th Avenue South in the area of 28th Street East, the police found two knit caps and two baseball caps, one with a Seattle Mariners logo and the other with a North Carolina Tarheels logo.
Police received a. tip which led them to Charles Williams (“Williams”), stepfather of Dwyon Tatum (“D.Tatum”). During a police interview with Williams he indicated that D. Tatum may have had something to do with Griffin’s shooting. Police also interviewed John Tatum (“J.Tatum”) D. Tatum’s brother. In a statement to police and in testimony before the grand jury, Tatum indicated that a number of young men, all members of the Rolling 60s Crips gang, including his brother D. Tatum, Byers, and two young men identified as Robert, a/k/a “Killer Bee,” and Dennis a/k/a “Little Cisco,” had been at his home on the afternoon of the murder. According to J. Tatum, the young men were smoking marijuana on his porch and trying on masks and baseball caps. He also indicated that his brother owned a baseball cap with a North Carolina logo and that “Little Cisco” owned a baseball cap with a Seattle Mariners logo.
At Byers’ trial, J. Tatum was a reluctant witness and his testimony was limited. He testified that his brother and the other young men were at his home on the day of the murder, that they were members of the Rolling 60s Crips gang, and that he had overheard them planning a robbery. He claimed to have no recollection of seeing Byers and the other young men trying on masks. J. Tatum also testified that when he arrived home from work that evening, after Griffin’s murder had taken place, he found a Seattle Mariners baseball cap, a North Carolina Ta-rheels baseball cap, and two knit masks on his doorstep. At Byers’ trial, the State contended that the baseball caps and masks found on J. Tatum’s doorstep were intended to send a message to J. Tatum and his wife, Sandra Tatum (“S.Tatum”) to “keep quiet or else.” Sometime after Griffin’s murder, J. and S. Tatum moved to a new location. Shortly after the move, a Rolling 60s Crips’ gang symbol was spray painted on the back of their house. The state contended that this gang symbol was intended to intimidate J. and S. Tatum.
*491Both Berry and Minor testified at Byers’ trial. In addition to their testimony concerning the events which took place at Griffin’s apartment on the afternoon of Griffin’s murder, each positively identified Byers as one of the gunmen involved in the robbery and murder. Berry identified Byers in a police photo line-up prior to trial and at trial. According to her testimony, one of the gunmen held a gun to her head and stole her purse. She testified that she got a good look at that gunman. From the witness stand Berry identified Byers as that gunman. Minor also identified Byers from a police photo line-up, but, at that time, stated that he could not be certain of his identification unless he saw Byers in person. Upon seeing Byers in person at trial, Minor positively identified Byers as one of the gunmen involved in the robbery and murder.
Rolling 60s Crips member D. Tatum was also charged in connection with Griffin’s murder and was tried separately. D. Tatum’s trial took place before Byers’ trial. D. Tatum testified on his own behalf at his trial and was ultimately acquitted. At Byers’ trial, the trial court sought to compel D. Tatum to testify and offered him use immunity. In response, D. Tatum explained that his life might be in danger if he testified against Byers. While D. Tatum claimed that he did not fear retaliation from Byers, he acknowledged that one of the rules of the Rolling 60s Crips was that gang members did not testify against each other. Because of D. Tatum’s refusal to testify after the grant of immunity, the trial court found that D. Tatum was an unavailable witness, that D. Tatum’s testimony from his trial (hereinafter “D. Tatum’s testimony”) was trustworthy, and that, because Byers procured D. Tatum’s unavailability, Byers waived his Sixth Amendment right to confront D. Tatum. As a result, the trial court, over Byers’ strong objection, permitted selected portions of D. Tatum’s testimony to be read to the jury at Byers’ trial.3
At Ms trial, Byers testified on his own behalf and denied any involvement in Griffin’s murder. He testified that he joined the Crips gang in Cleveland, where he grew up, that he met D. Tatum after moving to Minneapolis, and that he joined the Rolling 60s Crips around Christmas of 1994. He admitted that he had been with D. Tatum, “Killer Bee,” “Little Cisco,” and other Rolling 60s Crips members at J. Tatum’s apartment on the afternoon of the murder, but testified that he left the apartment before 5:00 p.m. and went to Brooklyn Center to spend the night at the home of his girlfriend, Tarsha Abron (“Abron”). Abron’s testimony supported Byers’ story that Byers was with her at the time of Griffin’s murder.
Byers appealed his conviction to the court of appeals which held that the admission of D. Tatum’s testimony was error because the testimony lacked “sufficient guarantees of trustworthiness” necessary for admission under Rule 804(b)(5) of the Minnesota Rules of Evidence and because, in finding that Byers “waived” his right to confrontation, the trial court failed to. honor Byers’ constitutional right. State v. Byers, 554 N.W.2d 744, 748-49 (Minn.App.1996). Although the court of appeals concluded that the admission of D. Tatum’s testimony was error, it held that the error was harmless beyond a reasonable doubt and affirmed Byers’ conviction. Id. at '749.
We review the trial court’s eviden-tiary rulings for an abuse of discretion, and it is well settled that we will not reverse a trial court’s findings unless those findings are clearly erroneous. State v. Starkey, 516 *492N.W.2d 918, 925 (Mmn.1994); State v. Kulseth, 333 N.W,2d 635, 637 (Minn.1983). We afford the trial court considerable discretion in admitting evidence. State v. Stallings, 478 N.W.2d 491, 496 (Minn.1991); State v. Glaze, 452 N.W.2d 655, 660 (Minn.1990).
An otherwise inadmissible hearsay statement may be admitted at trial if the statement fits within one of the exceptions to the hearsay rule set out in Rule 804 of the Minnesota Rules of Evidence. The exception called into question in this case is found in Rule 804(b)(5), the so-called “catchall” exception:
(5) Other Exceptions. A statement not specifically covered by any of the foregoing exceptions but having equivalent circumstantial guarantees of trustworthiness, if the court determines that (A) the statement is offered as evidence of a material fact; (B) the statement is more probative on the point for which it is offered than any other evidence which the proponent can procure through reasonable efforts; and (C) the general purposes of these rules and the interests of justice will best be served by admission of the statement into evidence. However, a statement may not be admitted under this exception unless the proponent of it makes known to the adverse party sufficiently in advance of trial or hearing to provide the adverse party with a fair opportunity to prepare to meet it, the proponent’s intention to offer the statement and the particulars of it, including the name, address, and present whereabouts of the declarant.
Minn. R. Evid. 804(b)(5). However, before any hearsay exception under Rule 804 applies, the declarant must be unavailable as a witness.
Therefore, in order for D. Tatum’s testimony to have been properly admitted at Byers’ trial, D. Tatum must have been unavailable as a witness at Byers’ trial and the testimony must have sufficient guarantees of trustworthiness. The issue of D. Tatum’s unavailability is not before us as the parties do not dispute that D. Tatum was “unavailable” to testify at Byers’ trial. Thus, we are left with the questions of whether the trial court abused its discretion in finding that D. Tatum’s testimony contained sufficient guarantees of trustworthiness and whether that finding was clearly erroneous.
Byers contends that D. Tatum’s testimony was untrustworthy in that D. Tatum, at the time of his testimony, had a strong motive to lie because testimony implicating Byers may have tended to exculpate Tatum at his own trial4 and that D. Tatum’s testimony about Byers’ involvement in the Griffin murder played an important part in the jury’s determination of guilt.5 We are not persuaded by this argument. In State v. Stallings, the trial court refused to admit statements made by an unavailable witness during sworn testimony at a pre-trial hearing. 478 N.W.2d at 494. The court of appeals reversed, reasoning that the “testimony satisfied the requirements of the ‘catchall’ exception because (a) the testimony was given under oath and was subject to cross-examination and (b) ‘due process concerns require admitting’ the testimony in order to counter the evidence admitted about [the witness’] ‘excited utterance’ to the police officer moments after the incident.” Stallings, 478 N.W.2d at 494. Noting that the trial court has considerable discretion in excluding evidence and that the refusal to admit evidence under the catchall exception “may properly be predicated upon * * * the presence of suspicious circumstances raising doubt as to the motives or accuracy of the declarant,” Stallings at 495-96 (quoting 4 D. Louisell and C. Mueller, Federal Evidence § 472 at 929-30 (1980)), we reversed. In doing so, we endorsed the “totality of the circumstances” approach for determining the trustworthiness, and therefore, the admissibility of otherwise inadmissible hearsay statements under the “catchall” ex*493ception. Id. at 495-96. This approach requires the reviewing court to look at:
[T]he character of the witness for truthfulness and honesty, and the availability of evidence on the issue; whether the testimony was given voluntarily, under oath, subject to cross-examination and a penalty for perjury; the witness’ relationship with both the defendant and the government and his motivation to testify before the grand jury; the extent to which the witness’ testimony reflects his personal knowledge; whether the witness ever recanted his testimony; the existence of corroborating evidence; and, the reasons for the witness’ unavailability.. •
Id. at 495-96 (quoting United States v. Snyder, 872 F.2d 1351, 1355-56 (7th Cir.1989)).
Prior to Stallings, we had applied this approach in State v. Hansen, 312 N.W.2d 96 (Minn.1981). In Hansen the trial court, under Minn. Rule 804(b)(5), admitted an unavailable witness’ out-of-court statement to the police at a criminal defendant’s trial. On appeal, this court concluded that the witness’ statement did “not withstand the careful examination necessary to determine whether it possessed] sufficient guarantees of trustworthiness,” Hansen, 312 N.W.2d at 101, because the statement was not made under oath, was not tested by cross-examination, was motivated by monetary reward, and was not corroborated. Id. at 102. Here, the trial court carefully examined the totality of the circumstances surrounding D. Tatum’s testimony. Based on that examination, the trial court, exercising its considerable discretion, found that D. Tatum’s testimony was trustworthy.
Using the factors we identified in Stallings, our careful examination of the totality of the circumstances surrounding D. Tatum’s testimony leads us to conclude that the trial court did not abuse its discretion in admitting the testimony. D. Tatum’s testimony was obtained under oath, was voluntary, subject to perjury, and was not recanted; the testimony was vigorously challenged by cross-examination6 and was not made as a result of any monetary reward; D. Tatum was unavailable to testify at Byers’ trial because of his relationship with Byers; at the time of D. Tatum’s testimony, both he and Byers were Rolling 60s Crips gang members and D. Tatum’s relationship with the government was hostile; and D. Tatum’s testimony was corroborated by Berry and Minor, two victims of the robbery who were present when Griffin was murdered, and who positively identified Byers as having been one of the intruders involved in the robbery and murder, but not the shooter. In addition, D. Tatum’s testimony was further corroborated by Amos, Officer Green, and other testimony from Berry. According to D. Tatum, Byers told him that he stole “her” [Berry’s] purse and subsequently threw it away. Berry testified that Byers held a gun to her head and stole her purse. Amos testified that one of the four young men she observed running down the alley was carrying a large purse. Officer Green stated that after having been discarded, the purse was recovered and turned in to the police. Looking at the totality of the circumstances surrounding D. Tatum’s testimony, we conclude that D. Tatum’s testimony contains the guarantees of trustworthiness necessary for admissibility under Rule 804(b)(5).
Having concluded that D. Tatum’s testimony was properly admitted under Rule 804(b)(5), its admissibility must still survive constitutional challenge under the Sixth Amendment’s confrontation clause. See Hansen, 312 N.W.2d at 102. On the record before us, D. Tatum’s testimony survives such a challenge. The test for determining whether the admission of a witness’ statement under a hearsay exception constitutes a violation of the confrontation clause is: is the declaration necessary, and is it reliable. Id. (citing Ohio v. Roberts, 448 U.S. 56, 65, 100 S.Ct. 2531, 2538-39, 65 L.Ed.2d 597 (1980)). *494The necessity requirement is met here as a result of D. Tatum’s unavailability due to his refusal to testify. The reliability requirement is also met. “Statements which are made under oath and subject to cross-examination may be sufficiently reliable to protect the values associated with the confrontation clause.” Hansen, 312 N.W.2d at 102 (citations omitted). Here, D. Tatum’s testimony was cross-examined, given under oath, and corroborated , by two eyewitnesses to the murder.7 The United States Supreme Court, in Mattox v. United States, 156 U.S. 237, 242-43, 15 S.Ct. 337, 339-40, 39 L.Ed. 409 (1895), noted that the “primary object” of the confrontation clause is to force a declarant to be cross-examined as well as “compelling him to stand face to face with the jury in order that they may * * * judge * * * whether he is worthy of belief.” Here, that primary object was met. At D. Tatum’s trial, D. Tatum testified on his own behalf, and a jury stood in judgment of him and found his testimony so believable that he was acquitted of any culpability in the Griffin murder. Under the facts presented by this case, we conclude that the admission of D. Tatum’s testimony survives Byers’ confrontation clause challenge.
Finally, we conclude that the trial court’s finding that Byers procured D. Tatum’s unavailability and, therefore, waived his right to object to the admission of D. Tatum’s testimony was not clearly erroneous. In Hansen, we said, “[t]o find a waiver based [solely] on a witness’ reluctance to testify, absent any evidence of threats attributable to defendant, would destroy the right of confrontation in nearly all cases of alleged crimes against persons.” 312 N.W.2d at 105. However, we also indicated that “a defendant who procures the absence of a witness by threats impliedly waives his right to confrontation.” Id. at 104. In concluding that the trial court did not err in finding that Byers waived his right to object to the admission of D. Tatum’s testimony, we do not overrule Hansen or hold that a waiver based solely on D. Tatum’s reluctance to testify is proper. Nor do we ignore “that courts must indulge every reasonable presumption against the loss of constitutional rights.” Illinois v. Allen, 397 U.S. 337, 343, 90 S.Ct. 1057, 1060, 25 L.Ed.2d 353 (1970). Rather, we simply recognize that, based on the record before us, it is clear that the trial court had ample evidence before it to find that Byers procured D. Tatum’s absence.
This is not a case where either the existence of the Rolling 60s Crips’ conspiracy of silence or Byers’ and D. Tatum’s participation in that conspiracy are based on speculation or surmise. The record is clear. Both D. Tatum and Byers were members of the Rolling 60s Crips; each was aware of, agreed to, and participated in the conspiracy of silence. Implicit in that conspiracy of silence was the threat of violence against any member who broke the agreement to remain silent. By agreeing in the first instance to the conspiracy of silence for their mutual aid and protection, each member of the Rolling 60s Crips, including Byers and D. Tatum, benefits from that agreement without necessarily having to resort to actual, or even threatened, violence. Through his participation in the Rolling 60s Crips’ conspiracy of silence, Byers procured D. Tatum’s absence as surely as if he had directly threatened or inflicted actual violence on D. Tatum.8
Further, if overt acts of witness intimidation are necessary in order to find that the defendant has waived his right to object to the admission of prior testimony of an unavailable witness, there is ample evidence in this record which supports the conclusion that Byers waived his right to object. Throughout his trial, Byers was attired in the “colors” of the Rolling 60s Crips. During the trial, the courtroom was empty of spectators until D. Tatum was called to testify. At that point, several young men, also dressed in the colors of the Rolling 60s Crips, appeared as spectators in the courtroom in what realistically can only be described as an effort to *495intimidate D. Tatum.9 This obvious, and obviously successful,10 effort on the part of the Rolling 60s Crips, including Byers, to intimidate D. Tatum should not benefit Byers.
If you can intimidate a witness in open court with impunity, there is no need to engage in violence or threats of violence. As a practical matter, if a defendant may procure a witness’ silence by agreement for the mutual aid and protection of both the witness and the defendant, as is the case here, there will never be a need to make direct threats or engage in actual violence, and the defendant will never suffer any adverse consequences as a result of his or her participation in the agreement. Accordingly, we recognize that a witness’ absence and silence may be procured by agreement as effectively as it can be by violence or threats of violence. Byers’ flagrant parading of his gang’s colors during the trial, the presence of other gang members at strategic times during the trial, and efforts to silence other prospective witnesses, taken as a whole, lead to the inescapable conclusion that Byers procured D. Tatum’s absence.
The record adequately demonstrates that D. Tatum’s testimony, when viewed in light of the “totality of the circumstances,” was trustworthy and reliable,11 and, therefore, admissible; that D. Tatum’s testimony survives challenge under the Sixth Amendment; and, that Byers waived his right to complain about the admission of D. Tatum’s testimony.
Affirmed as modified.
. The out-of-court statement consisted of selected portions of the co-defendant’s testimony from the co-defendant’s separate trial.
. One of the baseball caps had a Seattle Mariners logo and the other had a North Carolina Tarheels logo.
. The testimony read to the jury can be summarized as follows: D. Tatum testified that he and several other members of the Rolling 60s Crips gathered at his brother’s house on the day of the murder and smoked marijuana. They discussed robbing Griffin. According to D. Tatum, the idea for the robbery originated with Byers. D. Tatum testified that he told his fellow gang members that he did not want any part of robbing Griffin and that he went to the apartment of a friend who lived in the same building as Griffin rather than participate in the robbery. According to D. Tatum, he remained in the vicinity to see what was going to happen. What he saw, after a few minutes, was several men running through the alley behind Griffin’s apartment building, one of whom he was "pretty sure” was Byers. D. Tatum testified that Byers later admitted to him that Byers was one of the men who entered Griffin’s apartment and committed the robbery and murder, that "Killer Bee” was the one who pulled the trigger, that Byers had taken "her” [Berry's] purse, and that he had thrown the purse away.
. Byers testified that by implicating him in Griffin's murder, D. Tatum was merely trying to place the blame for Griffin’s murder on him in order to clear himself and to protect other gang members with whom D. Tatum had a closer relationship.-
. While it is true that the testimony may have played a role in the jury’s determination of guilt, it must be pointed out that were it not for D. Tatum's testimony, Byers might well have been convicted of first-degree murder, instead of the lesser offense of second-degree murder.
. While it is true that it was the State, and not Byers who cross-examined D. Tatum, the State had little reason to "hold back” in its cross-examination or to accept D. Tatum’s contention that Byers was involved in the Griffin murder. See Stallings, 478 N.W.2d at 495, n. 1. The record from D. Tatum’s trial demonstrates that, on cross-examination, the State challenged D. Tatum’s statement regarding Byers, questioned D. Tatum's own propensity to rob Griffin, and attempted to demonstrate to the jury that D. Tatum harbored ill-will towards Griffin.
. Further, the other factors discussed above which provide the guarantees of trustworthiness necessary for admission of D. Tatum’s testimony under Rule 804(b)(5) also serve to buttress D. Tatum’s testimony and increase its reliability.
. In some respects, a conspiracy of silence is more effective and more efficient than having to make threats of or engage in actual violence.
. In addition to the intimidation directed towards D. Tatum, the record reflects that S. Tatum, D. Tatum's sister-in-law, was crying and afraid to come into the courtroom to testify against Byers because of her fear that gang members were present.
. While D. Tatum denied that Byers had threatened him, he acknowledged that his testimony might cause him "problems with other people." Indeed, at one point in Byers’ trial, D. Tatum’s attorney requested that D. Tatum be allowed to leave the courtroom because he feared for D. Tatum’s personal safety.
. We note that assertions of "unreliability” grow pale in the long shadows of witness manipulation.
