OPINION
D.W. NELSON, Circuit Judge.On November 1, 1988, a Los Angeles County Superior Court jury convicted Michael Su Chia (“Chia”) of two counts of first degree murder and one count of attempted murder, as well as counts of second degree robbery and conspiracy to commit robbery. Chia’s conviction stemmed from a Drug Enforcement Agency (“DEA”) sting operation that went tragically wrong. Two DEA agents were killed when the targets of the sting operation decided to rob and murder the agents instead of consummating the drug deal. Chia, however, was not accused of being one of the shooters or of being present when the agents were murdered. Rather he was prosecuted as a co-conspirator, an aider and abettor, and an accomplice.
Chia’s defense hinged on explaining his relationship to the shooters and his interactions with them in the days and hours before the murders. Chia contends that, far from being a co-conspirator, he tried to talk one of the shooters, his good friend William Wei Wang (“Wang”), out of the plot. In support of his version of events, Chia sought to introduce at trial statements made by Wang to police after the shooting. The trial court excluded the statements as hearsay. Chia’s direct appeals claiming that the trial court’s exclusion of Wang’s statements violated Chia’s constitutional right to present a defense were denied, as were his collateral attacks on his conviction in state court and in the district court below.
The crux of the matter before us is the reliability of Wang’s statements. If Wang’s statements bear sufficient indicia of reliability and were crucial to Chia’s defense, then it was error for the trial court to exclude them. United States v. Lopez-Alvarez, 970 F.2d 583, 588 (9th Cir.1992); People v. Kaurish, 52 Cal.3d 648, 276 Cal.Rptr. 788, 802 P.2d 278, 308 (1990). The evidence is overwhelming that the statements were both reliable and crucial to Chia’s defense. We are left with a definite and firm conviction that a mistake was committed and that Chia’s fundamental due process rights were violated when the trial court excluded Wang’s statements.
We reverse the judgment of the district court and remand with instructions to grant the writ of habeas corpus unless the State grants Michael Chia a new trial within a reasonable time.
I.
On the evening of February 4, 1988, DEA agents were watching the apartment of Frank Kow (“Kow”), a major drug dealer. At 10:10 p.m. Michael Chia’s black Mitsubishi pulled up in front of Kow’s apartment complex. Chia and his friend, William Wang, got out of the Mitsubishi. Wang took a pistol from the rear of the car and walked into the apartment complex. A few minutes later, Chia went up the complex stairs, paced on the landing, and then stood at the top of the stairs for several minutes until Wang came out. Wang and Chia walked back to the Mitsubishi together. Later that night, Wang and Chia were seen together at a local night club.
The next day, drug dealer Kow called DEA agents who had been posing as buyers and leading him on towards a major sting. Kow told the agents to meet him at *103511:00 a.m. at a local restaurant. That same morning, DEA agents again saw Chia’s black Mitsubishi at Row’s apartment, first at 10:30 a.m. and a second time at 11:30 a.m. Shortly after 11:30 a.m. other DEA agents saw the Mitsubishi enter the parking lot of the restaurant where the rendezvous between Kow and the DEA agents posing as drug buyers was scheduled. Chia got out of his car and talked to Wang and to Mike Chen (“Chen”), who had both arrived at the restaurant parking lot. After speaking with Wang and Chen, Chia entered the restaurant. A few minutes later he reemerged, got back into his car and drove to the restaurant entrance where he conversed briefly with Kow. Chia then drove into a nearby alley. After a brief time, he drove back into the parking lot, stayed for a few minutes, drove out of the lot again, and then reentered.
Meanwhile, three DEA agents posing as drug dealers got into a Volvo in the restaurant parking lot with Kow and drove off. The agents carried a bag containing $80,000 in cash with which to consummate the sting buy from Kow. Kow did not know that the three “drug dealers” were actually DEA agents, and the agents did not know that Kow planned to rob them of the $80,000 rather than sell them drugs. Row’s partners in the plot to rob the agents, Chen and Wang, followed behind the Volvo in a red Nissan. After driving a short while, Kow directed the agents to pull over. Kow got out of the Volvo, stood beside the car, and pointed a gun at the agents. The agents raised their hands. Chen and Wang, in the Nissan, pulled up behind the stopped Volvo. Wang got out of the Nissan, drew his gun, and joined Kow standing next to the Volvo containing the three agents, still sitting with their hands up. Chen remained behind the wheel of the Nissan, ready to make a quick getaway. The agents gave the money bag to Wang and Kow. Wang and Kow then opened fire on the agents. Two of the agents were killed and the third was seriously wounded.
Kow and Wang fled the scene in the Nissan with Chen behind the wheel. Other DEA agents who had been in the area closed in and a car chase ensued. Kow fired at the pursuing agents from the fleeing Nissan. The agents rammed the Nissan and opened fire on the occupants of the disabled car. Kow and Chen were killed and Wang was seriously wounded. Shortly after the shootout, Chia was arrested nearby in his Mitsubishi. Three sets of handcuffs, three ski masks, and .45 caliber ammunition were found in Chia’s car. The owner of a gun shop testified that several weeks before the shootout Chia had entered his shop with a companion and that the companion had purchased .45 caliber ammunition.
II.
Having survived the ear chase and shootout, Wang made four separate statements to investigators.
The first statement was made to DEA agents before Wang was wheeled into surgery for treatment of nine gunshot wounds. The DEA agents took pains to insure that Wang understood that he was in danger of death before taking his statement. The agents believed that Wang’s statements would be admissible as a dying declaration in case he did not survive the surgery. Wang told the agents that he, Chen, and Kow had planned to rob the drug dealers, that he did not know that they were really DEA agents, and that he did not know of anyone other than himself, Kow, and Chen involved in the actual shooting. Wang admitted to shooting one of the agents three times with a revolver and admitted providing a .45 caliber pistol for the robbery.
*1036Wang made his second statement to a Pasadena police officer later that afternoon, following successful surgery. Wang admitted that he had planned to rob the “drug dealers” in conjunction with Kow and Chen. Wang admitted that he shot two of the agents. He provided details about the staging of the robbery, with the red Nissan following behind the Volvo.
Wang’s third statement was given to Pasadena police officers later that evening. The interview was tape recorded and the entire tape was admitted into evidence as a State prosecution exhibit and played for the jury at Wang’s subsequent trial. During this interview, the police officer asked about Michael Chia’s involvement. Wang had not previously mentioned Chia but had described the involvement of Chen and Kow in the plot. Wang said that Chia told him not to go through with the plan. When pressed by the investigator, Wang said that Chia was not involved in the plot and was not going to get any drugs or money. Wang said that Chia warned him that Chen and Kow might turn on him and rob him. The investigator, not Wang, returned repeatedly to the subject of Chia’s involvement. Wang repeated that Chia was not involved in the plot, although he knew about it. Wang said that Chia had dropped him off at Row’s apartment and was present later to protect Wang because he feared Kow and Chen would turn on him.
Wang’s fourth and final statement was given to the FBI two days after the shooting. Wang confessed that not only did he plan to rob the agents but that he knew in advance that Kow planned to kill the agents. Wang stated again that Chia told him not to go through with the plot. He also stated that when he spoke with Chia in the restaurant parking lot he had told Chia to go home, but Chia remained to look out for his safety. In response to questions, Wang said that the handcuffs found in Chia’s car belonged to an individual named Johnny Lee and that he did not know anything about the ski masks.
Wang’s description of his movements preceding the shootings was consistent with his prior statements to law enforcement officers and was consistent with the independent observations of DEA agents. Wang accurately described Chia taking him to Row’s apartment where Wang delivered a gun and ammunition and learned of the final plans for the robbery. He also accurately recounted that he went with Chia to a nightclub that evening, stayed the night with Chia at a friend’s house, and was dropped off by Chia at Row’s apartment the next morning.
III.
The district court’s decision to deny a 28 U.S.C. § 2254 habeas petition is reviewed de novo. Alvarado v. Hill, 252 F.3d 1066, 1068 (9th Cir.2001). Pursuant to the Antiterrorism and Effective Death Penalty Act of 1996 (“AEDPA”), 28 U.S.C. § 2254(d), a federal habeas court may grant a state prisoner’s application for a writ of habeas corpus with respect to claims adjudicated on the merits in state court only if the state court adjudication resulted in a decision that (1) was contrary to clearly established Federal law as determined by the Supreme Court of the United States, or (2) involved an unreasonable application of clearly established Federal law, as determined by the Supreme Court of the United States. Williams v. Taylor, 529 U.S. 362, 412, 120 S.Ct. 1495, 146 L.Ed.2d 389 (2000).
Under AEDPA “we must reverse a state court’s decision as involving an ‘unreasonable application’ of clearly established federal law when our independent review of the legal question does not merely allow us ultimately to conclude that the *1037petitioner has the better of two reasonable legal arguments, but rather leaves us with a ‘firm conviction’ that one answer, the one rejected by the court, was correct and the other, the application of the federal law that the court adopted, was erroneous — in other words that clear error occurred.” Van Tran v. Lindsey, 212 F.3d 1143, 1153—54 (9th Cir.), cert. denied, 531 U.S. 944, 121 S.Ct. 340, 148 L.Ed.2d 274 (2000).
IV.
It is clearly established federal law, as determined by the Supreme Court of the United States, that when a hearsay statement bears persuasive assurances of trustworthiness and is critical to the defense the exclusion of that statement may rise to the level of a constitutional due process violation. Chambers v. Mississippi 410 U.S. 284, 302, 93 S.Ct. 1038, 35 L.Ed.2d 297 (1973).
Under AEDPA, Ninth Circuit case law may be persuasive authority for deciding whether a state court decision unreasonably applied Supreme Court precedent, or it may help us determine what law is clearly established. Lindsey, 212 F.3d at 1154. In a habeas proceeding, we have traditionally applied a balancing test to determine whether the exclusion of evidence in the trial court violated petitioner’s due process rights, weighing the importance of the evidence against the state’s interest in exclusion. Miller v. Stagner, 757 F.2d 988, 994 (9th Cir.1985), amended on other grounds, 768 F.2d 1090 (9th Cir.1985). The court must give due weight to the substantial state interest in preserving orderly trials, in judicial efficiency, and in excluding unreliable evidence. Miller, 757 F.2d at 995.
When deciding whether an evidentiary rule violates the Due Process Clause or the Sixth Amendment, we apply a five-part balancing test. United States v. Duran, 41 F.3d 540, 545 (9th Cir.1994); Whelchel v. Washington, 232 F.3d 1197, 1211 (9th Cir.2000). The factors considered are (1) the probative value of the excluded evidence on the central issue; (2) its reliability; (3) whether it is capable of evaluation by the trier of fact; (4) whether it is the sole evidence on the issue or merely cumulative; and (5) whether it constitutes a major part of the attempted defense. Tinsley v. Borg, 895 F.2d 520, 530 (9th Cir.1990).
V.
Applying the Tinsley test to Wang’s statements, we conclude that the factors tip overwhelmingly in Chia’s favor. We may not reverse a state court decision simply because it is inconsistent with a rule established by a Ninth Circuit case. Lindsey, 212 F.3d at 1154. However, application of the Tinsley factors persuades us that Wang’s statements were clearly both reliable and crucial to Chia’s defense. Under Chambers, exclusion of these statements was an unreasonable application of clearly established federal law that violated Chia’s constitutional due process rights.
Wang’s Third Statement.
On the paramount issue of reliability (the second factor of the balancing test), the self-inculpatory nature of Wang’s statements weighs in favor of admission. The very words in this statement that exculpate Chia are highly inculpatory of Wang. Wang said that after he informed Chia of the plot, Chia tried to talk him out of it. This admission inculpates Wang by removing all doubt as to mens rea. Wang discussed the plot with his friend, was warned not to go through with it, and after plenty of time for reflection decided to go ahead anyway. At the same time, Chia’s warning establishes that he was not fur*1038thering the conspiracy but, quite the opposite, was discouraging his friend from participating. The inculpatory force of this statement with respect to Wang is obvious, and indeed the government conceded at oral argument that the very words, “he told me don’t do it,” at once inculpate Wang and exculpate Chia.
Self-inculpatory statements have long been recognized as bearing strong indicia of reliability. See, e.g., Fed. Rule Evid. 804(b)(3); Williamson v. United States, 512 U.S. 594, 599, 114 S.Ct. 2431, 129 L.Ed.2d 476 (1994) (“[Reasonable people, even reasonable people who are not especially honest, tend not to make self-inculpatory statements unless they believe them to be true.”). Wang’s third statement therefore bears strong indicia of reliability.
The first and fifth factors of the balancing test, the probative value of the excluded evidence on the central issue and whether it constitutes a major part of the attempted defense, also weigh in Chia’s favor. Chia’s whereabouts, movements, and actions before and during the commission of the crime are not disputed. The issue is whether his behavior was aimed at facilitating and encouraging the crime as the State contends, or at discouraging the crime and protecting his friend from harm. This question underlies Chia’s entire defense, and Wang’s statements are extremely probative on this point.
The third factor of the balancing test, whether the evidence is capable of evaluation by the trier of fact, is also satisfied. The jury heard evidence from the State’s expert that Chia’s observed behavior was consistent with “counter surveillance.” In other words, the State’s expert theorized that Chia’s actions were consistent with criminal behavior aimed at discovering and thwarting police efforts to detect the conspiracy. If Wang’s statements were introduced, the jury would be called upon to weigh the plausibility of the State’s theory against Wang’s testimony, which explained the events in a way that would not subject Chia to criminal liability. Such determinations are well within the province of the fact finder.
The fourth factor, whether the evidence is the sole evidence on the issue or merely cumulative, is also satisfied. Wang exercised his Fifth Amendment rights and refused to testify at Chia’s trial. Chia, as was his right, also declined to take the stand. Chia attempted, on cross examination of the State’s witnesses, to establish his explanation of events. However, he was not able to elicit testimony from those interested in convicting him that would establish his role in discouraging the conspiracy. Chia was left with Wang’s statements as the only means of establishing his role.
Chia’s third statement squarely satisfies all of the factors in the balancing test, and clearly should have been admitted.
Wang’s Other Statements.
Wang’s fourth statement adds the information that after Chia arrived at the restaurant parking lot, he told Wang not to go through with the crime. Wang, in turn, told Chia to go home. Chia remained, Wang said, to watch out for Wang’s safety, not to further the robbery. In the fourth statement, Wang also admits for the first time that he knew in advance that Kow planned to kill the “drug dealers” as well as rob them. In this statement, Wang admits to being warned not to go through with the crime at a time when he knew that murder was part of the plot. Wang admits an opportunity to back out, presumably with Chia driving him to safety in the black Mitsubishi, moments before the crime commenced. With each re-telling of events Wang recalls more detail (as he *1039recovers from surgery) and the statements become more self-inculpatory. As his statements progressively exonerate Chia, they also destroy any hope Wang might have for a defense or sentence mitigation based on lack of knowledge or intent.
Wang’s first and second statements do not directly exculpate Chia, although they do of course inculpate Wang. In these statements, Wang does not include Chia as he freely describes the planning and execution of the crime. This tends to show Chia was not involved. While the first statement does not technically meet the definition of a dying declaration, it was given when Wang knew that he was in real danger of imminent death, a traditional indicium of reliability.
The four statements that Wang gave to investigators form a picture of the crime from Wang’s point of view and the credibility of each assertion is enhanced by its context in Wang’s consistent depiction. All four statements are consistent with each other and consistent with the DEA’s observation of events. When the defendant is attempting to introduce an out-of-court statement, the corroboration of the contents of that statement with other evidence is a factor pointing toward reliability and admission. Chambers, 410 U.S. at 300, 93 S.Ct. 1038. Likewise, numerous consistent confessions corroborate each other. Id.
Taken as a whole, the four statements bear strong indicia of reliability and are crucial to Chia’s defense. The State’s interest in enforcing its hearsay rules “is based on experience and grounded in the notion that untrustworthy evidence should not be presented to the triers of fact.” Chambers, 410 U.S. at 298, 93 S.Ct. 1038. The evidence here bears strong indicators of trustworthiness. The inculpatory nature of Wang’s statements and the fact that his first statement was made while he was in imminent danger of death mark the statements with the same indicators of reliability that underlie traditional exceptions to the hearsay rule. On the particular facts of this case the State’s interest in excluding the evidence is minimal while the importance of the evidence is great. On the record before us, we are firmly convinced that a mistake was committed and that Wang’s statements should have been admitted into evidence.
VI.
A writ of habeas corpus is properly granted for a state court decision involving an unreasonable application of clearly established Federal law. 28 U.S.C. § 2254(d)(1). This standard includes a state-court decision that correctly identifies the governing legal rule but applies it unreasonably to the facts of a particular prisoner’s case. Williams, 529 U.S. at 407-08, 120 S.Ct. 1495.
In the present case, the trial court identified Chambers as the governing legal rule. Chambers held that when a hearsay statement bears persuasive assurances of trustworthiness and is critical to the defense it may not be excluded by a mechanistic application of state hearsay rules. Chambers, 410 U.S. at 302, 93 S.Ct. 1038.
As to the importance of Wang’s statements to the defense, the trial court accurately summarized what was at stake for Chia:
The activity of Mr. Chia, if taken by itself, is subject to two reasonable interpretations: one, that he was simply trying to help out the buddy and the other, of course, knowing full well what his buddy was doing, he was there to assist and to facilitate and to encourage and aid and abet and everything else.
Despite this clear statement of Chia’s position, the trial judge made the decision that *1040Wang’s statements did not clearly help the defense. We find this conclusion to be unreasonable. Wang stated that Chia told him not to do it and that Chia was not involved in furthering or encouraging the crime. These statements are clearly helpful to Chia. If believed by the jury, they exonerate Chia. While they also show that Chia knew of the plot in advance, mere knowledge is not sufficient to sustain a conviction under an accomplice theory.
As to the reliability of the statements, the court pronounced that the statements did not “match the [Cal. Evid.Code] 1230 definition” of reliability.1 The judge acknowledged that Wang’s statements could be admitted against Wang at his own trial as statements against penal interest. The judge also evinced understanding that the statements could be admitted against Wang because people tend not to make self-inculpatory statements unless they believe them to be true. But, the court noted, at that point Wang would be a party and a different rule would apply. The judge also observed, using his own hypothetical examples, that while a statement may be “a classic declaration against penal [interests]” it could still lack the reliability “that this particular section requires.” The judge further commented that he did not believe statements made “while you are in the clutches of the law” fall under § 1230.
Our analysis shows that Wang’s statements bear compelling indicia of reliability. The trial court engaged in a classic example of what Chambers prohibits: “[W]here constitutional rights directly affecting the ascertainment of guilt are implicated, the hearsay rule may not be applied mechanistically to defeat the ends of justice.” Chambers, 410 U.S. at 302, 93 S.Ct. 1038.
The judge’s distrust of post-arrest statements is also misplaced. The United States Supreme Court succinctly explained circumstances in which post-arrest statements are suspect: “Due to his strong motivation to implicate the defendant and to exonerate himself, a codefendant’s statements about what the defendant said or did are less credible than ordinary hearsay evidence.” Williamson, 512 U.S. at 601, 114 S.Ct. 2431. This rationale applies where the codefendant is inculpating the defendant in order to exonerate himself. Here Wang did just the opposite, exonerating Chia while inculpating himself.
The California Court of Appeal made the same error as the trial court when it pronounced Wang’s post-arrest statements unreliable, citing People v. Campa, 36 Cal.3d 870, 206 Cal.Rptr. 114, 686 P.2d 634, 640(1984). However, Campa identifies post-arrest statements as inherently suspect “where a declarant in police custody seeks to exculpate himself by implicating another suspect.” Id. Federal habeas corpus relief does not lie for errors of state law. Estelle v. McGuire, 502 U.S. 62, 67, 112 S.Ct. 475, 116 L.Ed.2d 385 (1991). We comment on Campa only to point out again that the reasoning behind suspicion of post-arrest statements obviously does not apply to the facts of this case.
*1041The present case is also distinguishable from LaGrand v. Stewart, 133 F.3d 1253 (9th Cir.1998). In LaGrand, Karl LaG-rand’s confession included two separate statements: first, Karl admitted that he stabbed the victim, and second, he said that Walter LaGrand did not stab anyone. We held that the exclusion of Karl’s confession in Walter’s trial did not violate Walter’s due process rights because “a statement that includes both incriminating declarations and corollary declarations that, taken alone, are not inculpatory of the declarant, must be separated and only that portion that is actually incriminating of the declarant admitted under the exception.” LaGrand, 133 F.3d at 1267-68 (citing Williamson, 512 U.S. at 599-600, 114 S.Ct. 2431). Here, the key portions of Wang’s statements that exculpate Chia are not corollary; they are directly inculpatory of Wang.
The trial court’s conclusion that Wang’s statements were inadmissible under Chambers was clear error and an unreasonable application of clearly established Federal law as determined by the Supreme Court of the United States.
VII.
For the foregoing reasons we conclude that Wang’s four statements were both reliable and crucial to Chia’s defense. Because the trial court’s exclusion of these statements was an unreasonable application of clearly established Federal law as determined by the Supreme Court of the, United States, the decision of the district court is REVERSED and the matter is REMANDED with instructions to GRANT the writ of habeas corpus unless the State grants Michael Chia a new trial within a reasonable time.
. Cal. Evid.Code § 1230 reads as follows: "Evidence of a statement by a declarant having sufficient knowledge of the subject is not made inadmissible by the hearsay rule if the declarant is unavailable as a witness and the statement, when made, was so far contrary to the declarant's pecuniary or proprietary interest, or so far subjected him to the risk of civil or criminal liability, or so far tended to render invalid a claim by him against another, or created such a risk of making him an object of hatred, ridicule, or social disgrace in the community, that a reasonable man in his position would not have made the statement unless he believed it to be true.”
