¶ 1. This case comes before us on remand from the Wisconsin Supreme Court. Roberto Vargas Rodriguez previously appealed from judgments of the circuit court for Milwaukee County convicting him of one count of battery, see Wis. Stat. § 940.19(1) (2005-06) ;1 one count of intimidation of a victim, see Wis. Stat. §§ 940.45(3) & 940.46; one count of intimidation of a witness, see Wis. Stat. §§ 940.42 & 940.46; and two counts of disorderly conduct, see Wis. Stat. § 947.01, all as an habitual criminal, see Wis. Stat. § 939.62, and from the trial court's order denying his motion for postconviction relief. State v. Rodriguez, 2006 WI App 163, ¶ 1, 295 Wis. 2d 801, 722 N.W.2d 136 (Rodriguez I).
¶ 2. In Rodriguez I, Rodriguez argued that the trial court denied him his right to confrontation of the victim and witness, Jill LaMoore and her daughter Casey, who did not appear at trial and erred in:
*132(1) permitting the State to ask Rodriguez's brother about his membership in a street gang; (2) overruling a defense objection to the prosecutor accusing Rodriguez of lying during his testimony; and (3) not recusing itself in connection with Rodriguez's postconviction motion asserting that he was prejudiced by his trial lawyer's alleged deficient representation. Rodriguez also argues that he was prejudiced by his trial lawyer's alleged deficient representation when the trial lawyer: (1) did not object when the prosecutor asked the police-officer witnesses whether there was anything else they wanted to tell the jury, and (2) asked one of the police officers whether he believed that Ms. LaMoore was telling the truth when she told him that Rodriguez had attacked her and Casey.
Id.
¶ 3. We affirmed on all grounds. Id. Rodriguez petitioned for review, which petition the supreme court held in abeyance pending its decision in State v. Jensen, 2007 WI 26, 299 Wis. 2d 267, 727 N.W.2d 518. The court subsequently remanded Rodriguez I to this court for reconsideration in light of Jensen.
¶ 4. Jensen further explains previous Wisconsin holdings describing when statements are subject to the United States and Wisconsin constitutional right of confrontation2 because they are testimonial as described in Crawford v. Washington, 541 U.S. 36 (2004).3 In addition, for the first time in Wisconsin, Jensen adopts the doctrine of forfeiture by wrongdoing, explains when confrontation rights may be forfeited because of *133misconduct by the person asserting the right to confrontation, and specifies how the determination of forfeiture is to be made by the trial court. See id., 299 Wis. 2d 267, ¶ 57. In Rodriguez I, the majority concluded that all statements were admissible under Crawford because they were not testimonial. Rodriguez I, 295 Wis. 2d 801, ¶¶ 27-28. Therefore, we did not consider whether Rodriguez had forfeited his right of confrontation by misconduct, including the effect of Rodriguez's convictions for intimidation of the victim and witness. See State v. Blalock, 150 Wis. 2d 688, 703, 442 N.W.2d 514 (Ct. App. 1989) ("[C]ases should be decided on the narrowest possible ground."). We now reconsider the right of confrontation portion of our decision in Rodriguez I in fight of Jensen.
I. Facts
¶ 5. The facts underlying the multiple convictions have been described in detail in Rodriguez I, and will not be repeated here except as necessary to this opinion. See id., 295 Wis. 2d 801, ¶¶ 3-11. Rodriguez was charged in the original criminal complaint with battery; his victims were Jill LaMoore, who was his girlfriend, and her daughter, who was seven years old. He was also charged with intimidation of a victim based upon a supporting affidavit that alleged that he threatened LaMoore with a "bloodbath" and that he would stab her if she ever called the police again.
¶ 6. On the original trial date, January 14, 2004, after a hearing at which Rodriguez and his counsel were present, the trial court issued an order which suspended all of Rodriguez's telephone, mail and visitation privileges (except with his attorney) because the court found the restrictions were "necessary to prevent further intimidation of witnesses." The State supported its request *134for the order with audiotapes of multiple telephone calls made by Rodriguez from the House of Correction in which Rodriguez urged his brother, Luis, to tell LaMoore not to testify. These conversations were recorded after Rodriguez had received both a written notice that this could occur and after an automated warning of the recording was given to Rodriguez before each of the recorded conversations. The audiotapes of twenty-one conversations demonstrate that Rodriguez repeatedly asked Luis to tell LaMoore "to not come to court and testify" against him. The recordings also establish that Luis indicated that he would "pay her [off]." Rodriguez eventually told Luis that he had "found" LaMoore.
¶ 7. The State subsequently filed an amended complaint, adding the additional charges of intimidation of a witness based upon Rodriguez's attempting to discourage LaMoore "from attending or giving testimony at trial." When the trial began on March 17, 2004, neither LaMoore nor her seven-year-old daughter appeared. Id., ¶ 2. The State indicated it had made approximately a dozen telephone calls to LaMoore, had written letters and had attempted to subpoena her before trial. The trial court found that the "State has made a due and diligent effort to get the victim here to court.... [T]he State has done everything they could to try to get her here." The trial court noted, apparently in reference to the intimidation charges, that "if the charges are true... the defendant... is part of why the victim is not here." Statements LaMoore made directly to police officers, and statements that her daughter made to her and to police officers,4 were admitted at trial through the testimony of the officers. Id., ¶¶ 3-11. Rodriguez objected to that *135testimony on confrontation grounds, based upon Crawford. Rodriguez I, 295 Wis. 2d 801, ¶ 2.
¶ 8. The House of Correction's logs of these telephone calls and the audiotapes of the conversations were admitted as evidence at trial, and played for the jury. The jury found Rodriguez guilty of intimidating LaMoore, both as a victim and as a witness.5
¶ 9. In Rodriguez I, Rodriguez argued that the statements by LaMoore and her daughter were testimonial and therefore inadmissible because he was unable to cross-examine the declarants. Not surprisingly, the State argued that the statements were not testimonial, but that if we concluded otherwise, then Rodriguez's conviction for witness intimidation forfeited his right to object to the same witness's hearsay testimony. Rodriguez responded that the State had waived that argument because it failed to argue forfeiture by wrongdoing at the trial court, and because application of the doctrine required the trial court to find that Rodriguez caused LaMoore's absence from trial. These arguments are renewed by the parties on remand.
II. Waiver
¶ 10. Rodriguez argues that forfeiture by wrongdoing was not argued by the State at the trial court level, and is therefore waived. We disagree.
¶ 11. The State did not name the doctrine during the January 2004 hearing, but it advised the trial court *136of Rodriguez's efforts to intimidate LaMoore as evidenced by the recorded telephone conversations. It also advised the trial court it would likely be charging Rodriguez with intimidation of a witness based upon those calls. The issue of Rodriguez's misconduct was before the trial court. At the time of that hearing, neither Davis v. Washington, 126 S. Ct. 2266 (2006), on a federal level, nor Jensen in Wisconsin, had yet been decided, endorsing the doctrine of forfeiture of the right of confrontation by wrongdoing. See Davis, 126 S. Ct. at 2280; Jensen, 299 Wis. 2d 267, ¶ 2. A litigant cannot fairly be held to have waived an argument that, at the time, a court of competent jurisdiction had not yet announced. See State v. Howard, 211 Wis. 2d 269, 287-88, 564 N.W.2d 753 (1997), overruled on other grounds by State v. Gordon, 2003 WI 69, 262 Wis. 2d 380, 663 N.W.2d 765.
¶ 12. Generally, we do not apply waiver against a respondent who is seeking to uphold a trial court ruling. See State v. Holt, 128 Wis. 2d 110, 124-26, 382 N.W.2d 679 (Ct. App. 1985). If, however, actions by the State prevented fact finding on an issue that could have been resolved, then waiver may be applied. See State v. Nichelson, 220 Wis. 2d 214, 230, 582 N.W.2d 460 (Ct. App. 1998). Here, the State did nothing to prevent necessary fact finding; on the contrary, the State initiated the process from which the trial court made the pretrial findings of witness intimidation that supported the order terminating Rodriguez's access to telephone, mail and visitors in order to prevent further intimidation.
III. Admissibility of absent witness statements
A. Impact of Jensen
¶ 13. The majority originally concluded in Rodriguez I that the statements were not testimonial and, *137therefore, were admissible under the third Crawford formulation6 because they were excited utterances. Rodriguez I, 295 Wis. 2d 801, ¶ 23. In reaching that conclusion, we considered the following: Davis; State v. Manuel, 2005 WI 75, 281 Wis. 2d 554, 697 N.W.2d 811; State v. Searcy, 2006 WI App 8, 288 Wis. 2d 804, 709 N.W.2d 497; State v. Hemphill,7 2005 WI App 248, 287 Wis. 2d 600, 707 N.W.2d 313; and State v. King, 2005 WI App 224, 287 Wis. 2d 756, 706 N.W.2d 181. Rodriguez I, 295 Wis. 2d 801, ¶¶ 12-26. We did not reach the question of whether Rodriguez forfeited his right of confrontation or whether the State waived that argument. See Blalock, 150 Wis. 2d at 703.
¶ 14. Jensen explains that the trial court is to determine before trial whether the defendant caused the unavailability of the witness. Id., 299 Wis. 2d 267, ¶ 51. The supreme court describes the process the trial *138court is to employ and the burden of proof to be assigned: "[W]e adopt a broad forfeiture by wrongdoing doctrine, and conclude that if the State can prove by a preponderance of the evidence that the accused caused the absence of the witness, the forfeiture by wrongdoing doctrine will apply to the confrontation rights of the defendant." Id., ¶ 57.
¶ 15. Under the doctrine of forfeiture by wrongdoing announced in Jensen, the statement of an absent witness is admissible against a defendant who the trial court determines by a preponderance of the evidence caused the witness's absence. Id. Applying the long-established legal definition of causation, the court must find that "the defendant's conduct was a substantial factor in producing" the absence of the witness, keeping in mind that "there may be more than one cause" of the witness's absence, and "the acts of two [or] more persons might jointly produce" the absence. See Wis JI— Criminal 901.8 Thus, a trial court need only determine that the defendant's actions were a cause of the witness's absence; defendant's conduct need not be the only cause. See State v. Block, 170 Wis. 2d 676, 683, 489 N.W.2d 715 (Ct. App. 1992) (intervening negligence of health care providers does not negate stabbing as a cause of death). Under the provisions of Wis. Stat. *139§§940.429 and 940.46,10 an attempt to intimidate a witness may be prosecuted as a completed act, and solicitation of an intermediary to perform the act of intimidation does not exonerate the person making the solicitation. See State v. Moore, 2006 WI App 61, ¶¶ 13, 24, 292 Wis. 2d 101, 713 N.W.2d 131.
¶ 16. If the statements of the absent witness were not testimonial, and were otherwise admissible (here, as an exception to the hearsay rule), the statements can be used at trial regardless of the conduct of the defendant in causing the absence of the witness. See Jensen, 299 Wis. 2d 267, ¶¶ 14-15 (citations omitted). We assume, without deciding, that the statements were testimonial. Consequently, we first determine whether forfeiture by wrongdoing has been established in this case by a preponderance of the evidence as required by Jensen. Id., 299 Wis. 2d 267, ¶ 57.
B. Forfeiture by wrongdoing
¶ 17. It is undisputed that LaMoore and her daughter did not appear at trial, either when trial was *140originally scheduled or when it actually commenced. This record contains abundant facts11 from which the trial court could be, and apparently was, satisfied "by the greater weight of the credible evidence"12 that Rodriguez either independently (e.g., his recorded statement while incarcerated that he "found" LaMoore), or Luis at Rodriguez's request (e.g., Luis's recorded statement that he would "pay her off') were a cause of LaMoore's failure to appear. The trial court's order, entered before the final trial date, terminated *141Rodriguez's telephone, mail and visitation privileges based upon a finding that the action was "necessary to prevent the further intimidation of witnesses." This is, in essence, a finding by the trial court by a preponderance of the credible evidence that Rodriguez had taken steps while being held at the House of Correction to intimidate LaMoore, who he knew to be a witness against him, that intimidation has already occurred (e.g., LaMoore did not appear at the trial date), and that the restrictions announced were necessary to attempt to prevent future intimidation. The finding of misconduct, coupled with LaMoore's failure to appear at the original or adjourned trial date, and the court's finding that the "State has made a due and diligent effort to get the victim here to court," satisfy the substantive requirements announced in Jensen. Id., ¶¶ 53-57.
*140The greater weight of the credible evidence means that the evidence in favor of a "yes" answer has more convincing power than the evidence opposed to it. Credible evidence means evidence you believe in light of reason and common sense.
"Reasonable certainty" means that you are persuaded based upon a rational consideration of the evidence. Absolute certainty is not required, but a guess is not enough to meet the burden of proof.
COMMENT
Case Law. Wisconsin law recognizes and requires differing degrees of persuasion for different types of cases. Thus, separate and distinct burdens exist for: (1) criminal cases (beyond a reasonable doubt); (2) civil cases with penal aspects or involving criminal type behavior (higher civil standard: to a reasonable certainty by evidence that is clear, satisfactory, and convincing); and (3) ordinary civil actions (ordinary civil standard to a reasonable certainty by the greater weight of the credible evidence).
*141¶ 18. Rodriguez argues that there is no proof of intimidation of a witness because Luis denies having passed on the message to LaMoore and because the State did not prove that Luis actually delivered the message. Such proof would compel the State either to find the missing witness and persuade her to testify about whether she was intimidated (which would remove Crawford confrontation issues because she would no longer be unavailable) or to persuade Luis to incriminate himself by admitting that he took action to intimidate the witness. We do not believe that Jensen imposes such impossible alternatives on the State, and that the impossibility of such alternatives may have also been a reason that Jensen requires proof only by a preponderance of credible evidence, i.e., that defendant's misconduct was a cause of the witness's absence is more likely than not. See, e.g., United States v. Saulter, 60 F.3d 270, 280 (7th Cir. 1995) (to prove by *142a preponderance of the evidence means that it is "more likely than not" that the examined action occurred).
¶ 19. What the jury found beyond a reasonable doubt, the trial court, as we have explained, earlier found by a preponderance of the evidence. The jury found that Rodriguez intimidated LaMoore as a victim and intimidated LaMoore as a witness. Those jury findings confirm the sufficiency of the evidence to support the trial court's earlier conclusion by a preponderance of the evidence that Rodriguez had intimidated LaMoore. We hold that where the jury finds beyond a reasonable doubt that the defendant intimidated the person who was a witness, the defendant has forfeited, by his own misconduct, his right to confront that witness.
¶ 20. Because we conclude that Rodriguez forfeited, by his wrongful conduct, his right to confront LaMoore and her daughter, we do not decide whether the statements by LaMoore or her daughter were testimonial. See Blalock, 150 Wis. 2d at 703. Except as modified herein, we reaffirm our opinion in Rodriguez I.
By the Court. — Judgments and order affirmed.
All references to the Wisconsin Statutes are to the 2005-06 version unless otherwise noted.
See U.S. Const, amend. VI; Wis. Const, art. I, § 7.
After deciding Crawford v. Washington, 541 U.S. 36 (2004), in Davis v. Washington, 126 S. Ct. 2266 (2006), the United States Supreme Court first endorsed the doctrine of forfeiture by wrongdoing as applied to prior witness testimony.
We do not consider whether, under State v. Jensen, 2007 WI 26, 299 Wis. 2d 267, 727 N.W.2d 518, there is a substantive difference between the statements of a seven-year-old child and *135those of an adult. Such distinctions, if any, were not argued by the parties in either the original briefs or on remand.
Rodriguez was also found guilty of battery and disorderly conduct, all as a habitual criminal. State v. Rodriguez, 2006 WI App 163, ¶ 1, 295 Wis. 2d 801, 722 N.W.2d 136 (Rodriguez I).
The three formulations of testimonial statements under Crawford, adopted in State v. Manuel, 2005 WI 75, 281 Wis. 2d 554, 697 N.W.2d 811, are:
(1) "[E]x parte in-court testimony or its functional equivalent— that is, material such as affidavits, custodial examinations, prior testimony that the defendant was unable to cross-examine, or similar pretrial statements that declarants would reasonably expect to be used prosecutorially."
(2) ”[E]xtrajudicial statements ... contained in formalized testimonial materials, such as affidavits, depositions, prior testimony, or confessions."
(3) "[Sltatements that were made under circumstances which would lead an objective witness reasonably to believe that the statement would be available for use at a later trial."
Id., ¶ 37 (citations to Crawford omitted; alterations in Manuel); see Rodriguez I, 295 Wis. 2d 801, ¶ 20.
Our supreme court, in Jensen, overruled State v. Hemphill, 2005 WI App 248, 287 Wis. 2d 600, 707 N.W.2d 313. Jensen, 299 Wis. 2d 267, ¶ 24 n.8.
Wisconsin JI — CRiminal 901, entitled "CAUSE," states, in pertinent part: " 'Cause means that the defendant's conduct was a substantial factor in producing (identify harm or consequence).
[There may be more than one cause of [the harm or consequence]. The act of one person alone might produce it, or the acts of two more persons might jointly produce it.]"
Wisconsin Stat. § 940.42 states, in pertinent part: "Intimidation of witnesses; misdemeanor. Except as provided in s. 940.43, whoever knowingly and maliciously prevents or dissuades, or who attempts to so prevent or dissuade any witness from attending or giving testimony at any trial, proceeding or inquiry authorized by law, is guilty of a Class A misdemeanor."
Wisconsin Stat. § 940.46 states, in pertinent part:
Attempt prosecuted as completed act. Whoever attempts the commission of any act prohibited under ss. 940.42 to 940.45 is guilty of the offense attempted without regard to the success or failure of the attempt. The fact that no person was injured physically or in fact intimidated is not a defense against any prosecution under ss. 940.42 to 940.45.
