OPINION
COCHRAN, J.,
delivered the opinion of the Court
in which PRICE, WOMACK, JOHNSON and ALCALA, JJ., joined.
We granted review of this case to determine whether the videotape procedures set out in Article 38.071, § 2,1 including the use of written interrogatories in lieu of live testimony and cross-examination, satisfy the Sixth Amendment rights of confrontation and cross-examination under the Su[317]*317preme Court’s Crawford2 line of cases.3 In this aggravated-sexual-assault-of-a-child prosecution, the court of appeals found “no error in the trial court’s decision to allow cross-examination through written questions only” and to admit the child complainant’s two videotaped interviews with a child-abuse forensic examiner instead of requiring live testimony.4
Although we agree that there must be balance between a defendant’s right to confrontation and a societal need to protect fragile and traumatized child victims, that balance cannot constitutionally be struck by the method set out in Section 2 of Article 38.071. On federal constitutional matters, we are obliged to follow the dictates of the United States Supreme Court regardless of our own notions.5 We therefore reverse the judgment of the court of appeals because it erroneously held that constitutionally adequate cross-examination can be done through the use of written interrogatories posed by a “neutral” forensic interviewer more than a year after the initial interview.6
I.
Three-year-old R.D. stayed with her great-grandmother for childcare. Appellant is R.D.’s great-uncle who, with his wife, moved into the great-grandmother’s home in the spring of 2007. In August of that year, R.D. started acting “strange” and “walking around like a zombie.” Her father asked her if anyone had touched her “cookie”-R.D.’s word for her vagina-and he named off various people that she had been around. When he named appellant, R.D. said, “Yes.”7 R.D.’s parents called the police.
A week later, R.D.’s family took her to The Bridge Advocacy Center, where a forensic interviewer videotaped an interview with R.D. Throughout most of the interview, R.D. was looking down at the pictures that she was vigorously coloring. She correctly answered some of the interviewer’s questions concerning her body parts and the identification of animals and colors, but she answered others incorrectly. She seemed uninterested in many of the interviewer’s questions and several times said that she wanted to go watch Spiderman on TV. When she couldn’t leave, she folded her arms and, at first, would not cooperate.
Eventually, she said that her aunt saw appellant touch her “cookie” and that her [318]*318grandmother saw him do it and “spanked” him for it. In fact, neither the aunt nor the grandmother had seen appellant touch the victim. R.D. was also examined by a sexual-assault nurse who found that her hymen was irregular and that this healed injury had been caused by penetration.
Before trial, the State filed a motion to request the trial court to find R.D. — -now five years old — unavailable to testify and to admit the videotaped interview instead. R.D.’s therapist testified and said that she believed that testifying in front of the appellant or testifying via closed circuit television would be harmful.8 She thought that submitting written interrogatories through a female interviewer was the “best option.” Over the appellant’s objection,9 the trial court ruled that R.D. was unavailable to testify and that defense counsel could submit written interrogatories to the forensic interviewer, who would ask those questions and any “follow up” ones in a second recorded interview.
At this second interview — conducted fifteen months after the first one — the forensic interviewer began by discussing the difference between the truth and a lie, and R.D. appeared to understand the difference. Nonetheless, she said more than [319]*319once that truthful statements were lies. During this interview, R.D. said that appellant put his finger in her “cookie” (as opposed to touching it as she had said fifteen months earlier). This time she said that neither her aunt nor her grandmother saw any sexual contact between her and appellant.
R.D. did not testify at trial, but the two videotaped interviews were admitted over appellant’s confrontation objection. The jury convicted appellant of both touching R.D.’s genitals and penetrating her genitals and sentenced him to life in prison on both counts.
On appeal, appellant argued that the denial of rigorous cross-examination denied him his right to confront the witness. The court of appeals agreed that R.D.’s out-of-court statements were testimonial, but concluded that the trial court did not err in allowing “cross-examination through written questions only.” 10
II.
A. Pre-Crawford Law on the Right to Confrontation.
The Confrontation Clause gives a criminal defendant the right “to be confronted with the witnesses against him.”11 In Coy v. Iowa,12 Justice Scalia explained that “[w]e have never doubted, therefore, that the Confrontation Clause guarantees the defendant a face-to-face meeting with witnesses appearing before the trier of fact.”13 In Maryland v. Craig,14 decided just two years later, the Supreme Court pulled back from that absolute position. It held that in some special cases, when the specific facts showed that there was a “compelling” state interest, the witness need not actually confront the defendant face-to-face as she testified, although the defendant must be able to see her as she testified and must be able to contemporaneously cross-examine her.15
Both Coy and Craig involved prosecutions for sexually assaulting a child. Coy was accused of molesting two thirteen-year-old girls who were having an outdoor sleepover in a neighboring yard.16 An Iowa statute allowed prosecutors to use a screen to shield child witnesses from see: ing the defendant as they testified.17 Most of the elements of the right of confrontation were preserved through this procedure, but the witnesses could not see the defendant and the defendant could not see the witnesses as they testified.18 And, perhaps most importantly, the jury could not see how the witnesses and the defendant interacted when each confronted the other.19 In a 6-2 decision, the Supreme Court held that this procedure violated the right to confrontation.20 Justice Scalia noted the compelling state interest of pro[320]*320tecting fragile children and other witnesses:
That face-to-face presence may, unfortunately, upset the truthful rape victim or abused child; but by the same token it may confound and undo the false accuser, or reveal the child coached by a malevolent adult. It is a truism that constitutional protections have costs.21
In Craig, however, the Supreme Court, in a 5-4 decision, upheld the use of a one-way closed-circuit television for questioning a six-year-old child in lieu of face-to-face confrontation in the courtroom itself.22 A Maryland statute authorized this procedure if the trial judge determined that “testimony by the child victim in the courtroom will result in the child suffering serious emotional distress such that the child cannot reasonably communicate.”23 Under this procedure, the defendant could see the child as she testified, but she could not see the defendant.
According to Justice O’Connor, this procedure did not violate the Confrontation Clause because that provision can be reduced to its “central concern,” which is “to ensure the reliability of the evidence against a criminal defendant by subjecting it to rigorous testing in the context of an adversary proceeding before the trier of fact.”24 Rigorous and contemporaneous cross-examination could, under some special circumstances, alleviate the need for face-to-face confrontation. The Court stressed that only the witness’s ability to confront the defendant face-to-face was affected — no other portion of the Sixth Amendment right of confrontation was compromised:
[The one-way closed-circuit television procedure] “(1) insures that the witness will give his statements under oath-thus impressing him with the seriousness of the matter and guarding against the lie by the possibility of a penalty for perjury; (2) forces the witness to submit to cross-examination, the ‘greatest legal engine ever invented for the discovery of truth’; [and] (3) permits the jury that is to decide the defendant’s fate to observe the demeanor of the witness in making his statement, thus aiding the jury in assessing his credibility.”25
Thus, the “combined effect of these elements of confrontation-physical presence, oath, cross-examination, and observation of demeanor by the trier of fact-serves the purposes of the Confrontation Clause by ensuring that evidence admitted against an accused is reliable and subject to the rigorous adversarial testing that is the norm of Anglo-American criminal proceedings.”26
[321]*321Justice Scalia, the author of Coy just two years earlier, wrote a scathing dissent that began, “Seldom has this Court failed so conspicuously to sustain a categorical guarantee of the Constitution against the tide of prevailing current opinion.”27 He stated,
The Sixth Amendment provides, with unmistakable clarity, that “[i]n all criminal prosecutions, the accused shall enjoy the right ... to be confronted with the witnesses against him.” The purpose of enshrining this protection in the Constitution was to assure that none of the many policy interests from time to time pursued by statutory law could overcome a defendant’s right to face his or her accusers in court.28
This language, that even compelling social policies may not override the Sixth Amendment right of confrontation, echoed Justice Scalia’s language in Coy. The Supreme Court has never overturned the holding in Craig, but, beginning with Crawford v. Washington,29 the Supreme Court has nibbled it into Swiss cheese by repeating the categorical nature of the right to confrontation in every one of its more recent cases.30
[322]*322B. The Right to Confrontation under Crawford.
Fourteen years after Craig, in Crawford v. Washington, the Supreme Court reiterated the categorical right of confrontation that it had set out in Coy. Justice Scalia, speaking for seven members of the Court,31 concluded that, “[w]here testimonial statements are at issue, the only indicium of reliability sufficient to satisfy constitutional demands is the one the Constitution actually prescribes: confrontation.” 32 The Court overruled its prior decision in Ohio v. Roberts,33 which allowed admission of “ex parte testimony upon a mere finding of reliability,” because that “malleable standard” failed to protect against “paradigmatic confrontation violations.”34
In examining the history of the Confrontation Clause, the Crawford Court explained that it was based on the English common-law tradition of “live testimony in court subject to adversarial testing.”35 This English system was in contrast to the European civil-law system that “condone[d] examination in private by judicial officers.”36 That is, the European inquisitorial system allows for ex paríe questioning, the use of written questions and answers, and ex parte depositions. Justice Scalia noted that even the earliest American decisions held that depositions or other prior testimony could be admitted against an accused only if he was present and had an opportunity to cross-examine the witness at the time the live testimony was given.37 That “prior opportunity to cross-examine” in person is both a “necessary” and “dispositive” requirement for the admission of testimonial statements under the Confrontation Clause.38 Justice Scalia warned that “under no circumstances” shall the defendant be deprived of “ ‘seeing the witness face to face, and ... subjecting him to the ordeal of cross-examination.’ ”39
In Crawford, the Court explained that “[t]he text of the Sixth Amendment does [323]*323not suggest any open-ended exceptions from the confrontation requirement to be developed by the courts.”40 Social policy, public policy, even grave practical difficulties of obtaining the witness for trial41 do not trump the categorical requirement. Rather, under Crawford,
Admitting statements deemed reliable by a judge is fundamentally at odds with the right of confrontation. To be sure, the Clause’s ultimate goal is to ensure reliability of evidence, but it is a procedural rather than a substantive guarantee. It commands, not that evidence be reliable, but that reliability be assessed in a particular manner: by testing in the crucible of cross-examination.42
The Crawford Court stated, “It is not enough to point out that most of the usual safeguards of the adversary process attend the statement, when the single safeguard missing is the one the Confrontation Clause demands.”43 Thus, when testimonial statements are at issue, and the de-clarant is not making those statements from the witness stand at trial, “the Sixth Amendment demands what the common law required: unavailability and a prior opportunity for cross-examination.”44
That prior opportunity for cross-examination must serve the same function as is normally accorded to adversarial cross-examination in the courtroom during trial:
Cross-examination is the principal means by which the believability of a witness and the truth of his testimony are tested. Subject always to the broad discretion of a trial judge to preclude repetitive and unduly harassing interrogation, the cross-examiner is not only permitted to delve into the witness’ story to test the witness’ perceptions and memory, but the cross-examiner has traditionally been allowed to impeach, ie., discredit, the witness.... [T]he exposure of a witness’ motivation in testifying is a proper and important function of the constitutionally protected right of cross-examination.45
C. Testimonial Statements under Crawford and its Progeny.
The question then became, “What out-of-court statements are ‘testimonial’ for purposes of the right of confrontation?” In Crawford, the Court did not fully resolve that issue, recognizing that there would be some “interim uncertainty” interpreting and applying the distinction between testimonial and nontestimonial statements.46 Two years later, in Davis v. Washington,47 the Supreme Court elaborated on that distinction:
[324]*324Statements are nontestimonial when made in the course of police interrogation under circumstances objectively indicating that the primary purpose of the interrogation is to enable police assistance to meet an ongoing emergency. They are testimonial when the circumstances objectively indicate that there is no such ongoing emergency, and that the primary purpose of the interrogation is to establish or prove past events potentially relevant to later criminal prosecution.48
Under Davis, (as well as the Supreme Court’s more recent confrontation decision, Michigan v. Bryant49) the primary focus in determining whether an out-of-court statement is “testimonial” is on the objective purpose of the interview or interrogation, not on the declarant’s expectations.50 If the objective purpose of the interview is to question a person about past events and that person’s statements about those past events would likely be relevant to a future criminal proceeding, then they are testimonial.51
D. Child-Abuse Forensic Interview Statements and Videotapes Are Testimonial and Are Inadmissible Unless the Child Testifies or the Defendant Had a Prior Opportunity to Cross-Examine the Child.
Virtually all courts that have reviewed the admissibility of forensic child-interview statements or videotapes after the Davis decision have found them to be “testimonial” and inadmissible unless the child testifies at trial or the defendant had a prior opportunity for cross-examination.52 Indeed, in this case, the State does [325]*325not dispute that R.D.’s statements, made during her two interviews at The Bridge Children’s Advocacy Center, were testimonial, and the court of appeals explicitly held that they were testimonial.53
1. A prior opportunity to cross-examine means an opportunity for full personal adversarial cross-examination, including attacks on credibility.
Therefore, the Confrontation Clause question in this case is whether appellant had “a prior opportunity to cross-examine” R.D., as is required under Crawford. The court of appeals quite appropriately cited Davis v. Alaska54 for the proposition that the right of confrontation includes “not only the right to face-to-face confrontation, but also the right to meaningful and effective cross-examination.”55 And the court aptly cited Dean Wigmore, who had explained that the “‘main and essential purpose’ ” of confrontation is “the opportunity for cross-examination through the process of putting direct and personal questions to the witnesses and the obtaining of immediate answers.”56
Indeed, it is that personal presence of the defendant and the right to ask probing, adversarial cross-examination questions that lies at the core of an American criminal trial’s truth-seeking function. As the Supreme Court stated in California v. Green,57 a 1970 Confrontation Clause case, [326]*326the right of confrontation forces the witness to submit to cross-examination, the “ ‘greatest legal engine ever invented for the discovery of truth.’ ”58
Over one hundred years ago, Dean Wig-more waxed eloquent over the special sanctity of cross-examination in the American system of justice: “[Cjross-examination, not trial by jury, is the great and permanent contribution of the Anglo-American system of law to improved methods of trial procedure.”59 And that right of personal and open cross-examination had been well established in English common law. According to Sir Matthew Hale in 1680, “by this course of personal and open examination, there is opportunity for all persons concerned, viz. the judge, or any of the jury, or parties, or their council or attorneys, to propound occasional questions, which beats and bouts out the truth much better than when the witness only delivers a formal series of his knowledge without being interrogated.”60 One important objective of cross-examination is to test the veracity of the witness, “[b]ut even when all suspicion of veracity is supposed to be out of the question, how very unsatisfactory is the ‘ex parte ’ account of a witness taken under circumstances in which the adverse party had not a fair opportunity of cross-examination.”61
Cross-examination means
[t]he questioning of a witness upon a trial or hearing by the party opposed to the party who called the witness to testify. The purpose of cross-examination is to discredit a witness before the factfin-der in any of several ways, as by bringing out contradictions and improbabilities in earlier testimony, by suggesting doubts to the witness, and by trapping the witness into admissions that weaken the testimony.62
It is an examination by the opposing party, not a “neutral” interviewer. It occurs in the formal setting — a trial or a hearing.63 First the witness testifies. Then, cross-examination follows upon its heels.64 The cross-examiner may discredit the witness’s direct testimony in several different ways, depending upon the witness, the questioner, and the specific situation as it unfolds in the hearing. Both the federal and Texas hearsay rules apply to prior out-of-court statements made by a testifying witness.65
[327]*327The rationale for this rule is that a deferred opportunity to cross-examine is thought to be distinctly inferior to contemporaneous cross-examination:
The chief merit of cross examination is not that at some future time it gives the party opponent the right to dissect adverse testimony. Its principal virtue is in its immediate application of the testing process. Its strokes fall while the iron is hot. False testimony is apt to harden and become unyielding to the blows of truth in proportion as the witness has opportunity for reconsideration and influence by the suggestions of others, whose interest may be, and often is, to maintain falsehood rather than truth.66
Many of the post-Crawford child-abuse videotape cases that have been reversed involved statutory or judicial procedures that allowed the admission of testimonial hearsay statements without any cross-examination or an insufficient opportunity for cross-examination.67 For example, in State v. Contreras,68 the Florida Supreme Court held that the state’s statutory procedures regarding discovery depositions provided an inadequate opportunity for cross-examination because, inter alia, they may be taken without the defendant’s personal presence. These depositions do “not function as the equivalent of the cross-examination opportunity envisioned by Crawford.” 69 Indeed, even in Wigmore’s day, depositions did not provide a sufficient opportunity for cross-examination unless they were taken in “a formal proceeding governed by a settled procedure and enforced by vested authority.”70 Informal interviews, whether transcribed or recorded, do not provide the appropriate solemnity to qualify as an opportunity -for formal cross-examination.71 And ex parte depositions are strictly inadmissible; “[t]his is universally conceded as a common-law principle.”72
Similarly, in People v. Fry,73 the Colorado Supreme Court held that testimony taken at a preliminary hearing — hearings that are usually restricted to an assessment of probable cause and limit the defendant’s [328]*328right of cross-examination on credibility issues — is not admissible at trial. The preliminary hearing does “not provide an adequate opportunity to cross-examine sufficient to satisfy the Confrontation Clause requirements.”74
2. Ex parte submission of written interrogatories does not qualify as cross-examination.
The State argues that it “has an important public policy interest in protecting the physical and psychological well-being of children and, in particular, child abuse victims.”75 Therefore, argues the State, the trial court was “justified in requiring cross-examination by written interrogatories for the safety and protection of the child.”76 Although the State argues that there should be more flexibility in child-abuse cases, the Supreme Court has rejected the notion that there should be more flexibility concerning the Confrontation Clause in certain types of cases, such as domestic-abuse prosecutions. In Davis, Justice Scalia said:
Respondents in both cases [Davis and Hammon v. State, 829 N.E.2d 444 (Ind.2005)], joined by a number of their amici, contend that the nature of the offenses charged in these two cases— domestic violence — requires greater flexibility in the use of testimonial evidence. This particular type of crime is notoriously susceptible to intimidation or coercion of the victim to ensure that she does not testify at trial. When this occurs, the Confrontation Clause gives the criminal a windfall. We may not, however, vitiate constitutional guarantees when they have the effect of allowing the guilty to go free.77
The content of the constitutional rights to confrontation and cross-examination do not depend upon the type of crime charged or the fragility of the witnesses; all accused citizens are entitled to the full protection of the constitution.
Furthermore, the Crawford decision made clear that direct and personal cross-examination, with counsel’s ability to ask follow-up questions, is essential “to tease [329]*329out the truth” at trial.78 Thus, the Crawford Court stated that depositions or other prior testimony could be admitted against an accused only if he was present and had an opportunity to cross-examine during that deposition or prior testimony.79 And, in ringing terms, the Supreme Court declared that, “ ‘under no circumstances’ ” shall the defendant be deprived of “ ‘seeing the witness face to face, and ... subjecting him to the ordeal of a cross-examination.’ ”80 In the context of battered women, small children, and other fragile witnesses, this is a heavy price to pay, but it is the price that our constitution and our Supreme Court requires. There is no “balancing” the defendant’s constitutional right of confrontation and cross-examination against other social policies, even compelling ones.
III.
The court of appeals in this case, without citing to any of the Crawford line of cases, concluded that written interrogatories, propounded by a forensic child-sexual-abuse examiner some fifteen months after the child’s initial videotaped interview that the State wished to introduce, were a sufficient substitute for live, adversarial cross-examination to satisfy a defendant’s right to confrontation.81 But we are “not free to conduct a cost-benefit analysis of clear and explicit constitutional guarantees, and then to adjust their meaning to comport with our findings.”82 Cross-examination means personal, live, adversarial questioning in a formal setting. It cannot have one meaning for some witnesses and another meaning for others.
We are unable to find any post-Crawford precedent from any jurisdiction that states, or even suggests, that a list of ■written interrogatories, posed by a forensic examiner to a child in an ex parte interview, is a constitutional substitute for live cross-examination and confrontation.83
[330]*330Had he been forced to accept such a pallid substitute for the real thing, Sir Walter Raleigh would once more rattle his chains and cry out from the Star Chamber, “[L]et Cobham be here, let him speak it. Call my accuser before my facet.]”84 A few written interrogatories sent off to the Tower for the warden to ask Lord Cobham in his cell would not satisfy Sir Walter or the Confrontation Clause his trial engendered.
The ex parte “written interrogatory” procedure used in this case would not pass muster under Craig, the very case that the State and the court of appeals relied upon. In Craig, the majority held that the right of confrontation was not unconstitutionally gouged because every other aspect of the right to confrontation except face-to-face confrontation in the courtroom was given full force.85 Craig did require that the child testify under oath, be subject to full contemporaneous cross-examination, and be observed by the judge, jury, and defendant during that testimony.86 The only reason that the closed-circuit television procedure was permitted in Craig was because “the Confrontation Clause does not prohibit use of a procedure that, despite the absence of face-to-face confrontation, ensures the reliability of the evidence by subjecting it to rigorous adversarial testing and thereby preserves the essence of effective confrontation.”87
[331]*331There was no “rigorous adversarial testing” of R.D.’s testimonial statements by that greatest legal engine for uncovering the truth: contemporaneous cross-examination. The written-interrogatories procedure used in this case does not pass muster under our English common-law adversarial system or our United States Constitution. The constitutional requirement of confrontation and cross-examination “may not [be] disregarded] ... at our convenience,” regardless of the prediction of dire consequences.88
We therefore reverse the judgment of the court of appeals and remand this case to that court for further proceedings consistent with this opinion.
