BURKE, Justice.
More than five years ago, in
Mallott v. State,
608 P.2d 737 (Alaska 1980), we informed Alaska law enforcement officials that “it is incumbent upon them to tape record, where feasible, any questioning [of criminal suspects,] and particularly that which occurs in a place of detention.”
Id.
at 743 n.5 (citation omitted). This requirement (hereinafter the
Mallott
rule) was again noted in
S.B. v. State,
614 P.2d 786 (Alaska 1980), with the observation that an electronic record of such interviews “will be a great aid” when courts are called upon to determine “the circumstances of a confession or other waiver of [a suspect’s]
Miranda
rights.”
Id.
at 790 n.9. In a third case,
McMahan v. State,
617 P.2d 494 (Alaska 1980),
cert. denied,
454 U.S. 839,
102 S.Ct. 146, 70 L.Ed.2d 121 (1981), the recording requirement was repeated, with the further statement that “if
Miranda
rights are read to the defendant, this too should be recorded.” 617 P.2d at 499 n.11. Today, we hold that an unexcused failure to electronically record a custodial interrogation conducted in a place of detention violates a suspect’s right to due process, under the Alaska Constitution,
and that any statement thus obtained is generally inadmissible.
I. FACTS
The relevant facts in the two cases now before us are similar. Malcolm Scott Harris and Donald Stephan, petitioners, were arrested on unrelated criminal charges, taken to police stations and questioned by police officers. Harris was interrogated on two separate occasions; Stephan was interrogated, only once. Both men made incul-patory statements. In each instance, a working audio or video recorder was in the room and was used during part, but not all, of the interrogation. The officers, in each case, offered no satisfactory excuse for their clear disregard of the
Mallott
rule.
II. PROCEEDINGS BELOW
Prior to their respective trials, Harris and Stephan both moved to suppress confessions made during their interrogations. At the suppression hearings there was conflicting testimony about what occurred during the unrecorded portions of the interviews. Harris claimed that, in his first interrogation, he was not informed of his
Miranda
rights
at the beginning of the session, that the questioning continued after he asserted his right to remain silent, and that the officer made threats and promises during the untaped portions. Stephan claimed that his ultimate confession was induced by promises of leniency and was obtained in the absence of an attorney, after he requested one. In both cases, the officers’ testimony was to the contrary.
Without a full recording to resolve the conflict, the superior court was required to evaluate the credibility of the witnesses and choose which version of the unrecorded events to believe. In each case, the court chose the police officers’ recollections and determined that the confession was voluntary and, thus, admissible at trial.
Harris
and Stephan were ultimately found guilty and filed notices of appeal.
The Alaska Court of Appeals
concluded, in each case, that there was a violation of the
Mallott
rule, but declined to adopt an exclusionary rule. Both convictions were affirmed. Harris and Stephan petitioned this court for hearing, pursuant to Appellate Rule 302, and their petitions were granted. Given the factual similarities and the common legal issue, we ordered the two cases consolidated.
III. RECORDING IS A REQUIREMENT OF STATE DUE PROCESS
In its decision, the court of appeals acknowledged: “[T]he supreme court has clearly stated in three separate cases that the police are under a duty to record statements which suspects make where recording is feasible. That admonition cannot be ignored.”
Harris v. State,
678 P.2d 397, 404 (Alaska App.1984).
The court, nevertheless, refused to adopt a general exclusionary rule, stating:
[W]e believe that the issue of what sanction is appropriate is best approached on a case by case basis.... Exactly what sanction, if any, to apply for the failure to record a defendant’s statement in a given case is a decision which is best left to the sound discretion of the trial court under the standards set forth in
Putnam v. State,
629 P.2d 35, 43-44 (Alaska 1980).
Id.
at 404-05
The court of appeals’ refusal to adopt an exclusionary rule in these circumstances is perhaps due to failure on our part to adequately explain the full significance of our prior decisions. Electronic recording of suspect interrogations was described in those cases, rather ambiguously, as “part of [a law enforcement agency’s] duty to preserve evidence.”
Mallott v. State,
608 P.2d at 743 n.5 (citing
Catlett v. State,
585 P.2d 553, 558 n. 5 (Alaska 1978)).
Today, we resolve that ambiguity. Such recording is a requirement of state due process when the interrogation occurs in a place of detention and recording is feasible.
We reach this conclusion because we are convinced that recording, in such circumstances, is now a reasonable and necessary safeguard, essential to the adequate protection of the accused’s right to counsel, his right against self incrimina
tion and, ultimately, his right to a fair trial.
It must be emphasized that
our holding is based entirely upon the requirements of article I, section 7, of the Alaska Constitution,
as interpreted by this court.
See Michigan v. Long,
463 U.S. 1032, 103 S.Ct. 3469, 77 L.Ed.2d 1201 (1983) (a state court’s reliance on federal authority will be presumed, unless its reliance on independent state grounds is clear from the face of the court’s opinion). We accept the state’s argument that custodial interrogations need not be recorded to satisfy the due process requirements of the United States Constitution, because a recording does not meet the standard of constitutional materiality recently enunciated by the United States Supreme Court in
California v. Trombetta,
467 U.S. 479, 104 S.Ct. 2528, 81 L.Ed.2d 413 (1984).
In interpreting the due process clause of the Alaska Constitution, however, we “remain free to adopt more rigorous safeguards governing the admissibility of ... evidence than those imposed by the Federal Constitution.” 467 U.S. at -, 104 S.Ct. at 2535 n. 12, 81 L.Ed.2d at 423-24 n.12.
Thus, as we have done on previous occasions, we construe Alaska’s constitutional provision, in this instance, as affording rights beyond those guaranteed by the United States Constitution.
See State v. Glass,
583 P.2d 872, 876 n.12 (Alaska 1978)
modified by City and Borough of Juneau v. Quinto,
684 P.2d 127 (Alaska 1984) (warrant requirement applied to electronic monitoring of a police informant’s conversations with a suspect).
In
Municipality of Anchorage v. Serrano,
649 P.2d 256 (Alaska App.1982), the Alaska Court of Appeals extended the state’s duty to preserve evidence to include breath samples taken during the administration of a breathalyzer test. Given the importance of breath samples in cases involving a charge of driving while intoxicated, and the minimal cost and effort involved in obtaining them, the court of appeals explicitly held that the due process clause of the Alaska Constitution requires the state to gather and preserve a defendant’s breath sample.
Id.
at 258. The need to insure that the voluntariness of a confession can be confirmed by reference to an accurate and complete record is at least as important as the need to insure that the validity of breathalyzer test results can be independently tested. Given the relative ease with which such confirmation can be provided, by means of an electronic recording, we see no legitimate reason not to require it, at least to the extent mandated by this opinion.
When a defendant claims that his confession is involuntary, the Constitution of the United States imposes a heavy burden. Before the confession will be admitted, the prosecution must show a knowing and intelligent waiver of the defendant’s federal privilege against self incrimination and his right to counsel.
Miranda v. Arizona,
384 U.S. 436, 475, 86 S.Ct. 1602, 1628,
16 L.Ed.2d 694, 724 (1966). Under the Alaska Constitution, the state’s obligation is no less burdensome.
The contents of an interrogation are obviously material in determining the volun-tariness of a confession. The state usually attempts to show voluntariness through the interrogating officer’s testimony that the defendant’s constitutional rights were protected. .The defendant, on the other hand, often testifies to the contrary. The result, then, is a swearing match between the law enforcement official and the defendant, which the courts must resolve.
The difficulty in depicting what transpires at such interrogations stems from the fact that in this country they have largely taken place incommunicado.
... Interrogation still takes place in privacy. Privacy results in secrecy and this in turn results in a gap in our knowledge as to what in fact goes on in the interrogation rooms.
Miranda,
384 U.S. at 445, 448, 86 S.Ct. at 1612, 1614, 16 L.Ed.2d at 707, 709. Thus, we believe a recording requirement is justified, because “a tape recording provides an objective means for evaluating what occurred during interrogation.”
Harris v. State,
678 P.2d at 414 (Singleton, J., concurring and dissenting).
Although there are undoubtedly cases where the testimony on one side or the other is intentionally false, dishonesty is not our main concern. Human memory is often faulty — people forget specific facts, or reconstruct and interpret past events differently.
It is not because a police officer is more dishonest than the rest of us that we ... demand an objective recordation of the critical events. Rather, it is because we are entitled to assume that he is no less human — no less inclined to reconstruct and interpret past events in a light most favorable to himself — that we should not permit him to be a “judge of his own cause.”
Kamisar, supra
note 2, at 242-43 (citation omitted). Defendants, undoubtedly, are equally fallible.
In the absence of an accurate record, the accused may suffer an infringement upon his right to remain silent and to have counsel present during the interrogation. Also, his right to a fair trial may be violated, if an illegally obtained, and possibly false, confession is subsequently admitted. An electronic recording, thus, protects the defendant’s constitutional rights, by providing an objective means for him to corroborate his testimony concerning the circumstances of the confession.
The recording of custodial interrogations is not, however, a measure intended to protect only the accused; a recording also protects the public’s interest in honest and effective law enforcement, and the individual interests of those police officers wrongfully accused of improper tactics. A recording, in many cases, will aid law enforcement efforts, by confirming the content and the voluntariness of a confession, when a defendant changes his testimony or claims falsely that his constitutional rights were violated. In any case, a recording will help trial and appellate courts to ascertain the truth.
The concept of due process is not static; among other things, it must change to keep pace with new technological developments. For example, the gathering and preservation of breath samples was previously impractical. Now that this procedure is tech
nologically feasible, many states require it, either as a matter of due process or by resort to reasoning akin to a due process analysis.
The use of audio and video tapes is even more commonplace in today’s society. The police already make use of recording devices in circumstances when it is to their advantage to do so. Examples would be the routine video recording of suspect behavior in drunk driving cases and, as was done in these cases, the recording of formal confessions. Furthermore, media reports indicate that many Alaska police officers have purchased their own recorders, carry them while on duty and regularly record conversations with suspects or witnesses, in order to protect themselves against false accusations.
When a portable recorder has not been available, some officers have even used their patrol car radio to record conversations through the police dispatch center.
In both of the cases before us, the police were engaged in custodial interrogations of suspects in a place of detention. A working recording device was readily available, but was used to record only part of the questioning. Compliance with the recording rule is not unduly burdensome under these circumstances. Turning the recorder on a few minutes earlier entails minimal cost and effort. In return, less time, money and resources would have been consumed in resolving the disputes that arose over the events that occurred during the interrogations.
The only real reason advanced by police for their frequent failure to electronically record an entire interrogation is their claim that recordings tend to have a “chilling effect” on a suspect’s willingness to talk. Given the fact that an accused has a constitutional right to remain silent, under both the state and federal constitutions, and that he must be clearly warned of that right prior to any custodial interrogation, this argument is not persuasive.
In summary, the rule that we adopt today requires that custodial interrogations in a place of detention, including the giving of the accused’s
Miranda
rights, must be electronically recorded. To satisfy this due process requirement, the recording must clearly indicate that it recounts the entire interview. Thus, explanations should be given at the beginning, the end and before and after any interruptions in the recording, so that courts are not left to speculate about what took place.
Since its announcement, the
Mallott
rule has always included a proviso, “when feasible.” The failure to electronically record an entire custodial interrogation will, therefore, be considered a violation of the rule, and subject to exclusion,
only if the failure is unexcused.
Acceptable excuses might include an unavoidable power or equipment failure, or a situation where the suspect refused to answer any questions if the conversation is being recorded.
We need not anticipate all such possible excuses here, for courts must carefully scrutinize each situation on a case-by-case basis. Any time a full recording is not made, however, the state must persuade the trial court, by a preponderance of the evidence, that recording was not feasible under the circumstances,
and in
such cases the failure to record should be viewed with distrust.
IV. REMEDY
The court of appeals, in
Harris,
679 P.2d at 405, concluded that the determination of the appropriate “sanction” for a violation of the
Mallott
rule is best left to the sound discretion of the trial court, under the standards set forth in
Putnam v. State,
629 P.2d 35, 43-44 (Alaska 1980).
We, however, reject this choice of remedy. Instead, we adopt a general rule of exclusion. While other remedies may each have their merits, we believe an exclusionary rule will best protect the suspects’ constitutional rights, provide clear direction to law enforcement agencies and lower courts, and preserve the integrity of our justice system.
In
State v. Sundberg,
611 P.2d 44 (Alaska 1980), we declined to apply an exclusionary rule to violations of the forcible arrest statute (AS 12.25.080). In the absence of a history of excessive force in arrests, we were persuaded that application of an exclusionary rule would, at best, achieve only a marginal deterrent effect. The record in the present cases, however, shows that law enforcement agencies and lower courts have repeatedly failed to give due regard to the protections the
Mallott
rule is intended to provide, even though the rule was first announced over five years ago.
We believe that a strong and certain remedy will have a considerable deterrent effect in future cases. Compliance imposes such minimal costs and burdens on law enforcement agencies that they will have little to gain from noncompliance.
Another reason we were unwilling to apply the exclusionary rule in
Sundberg
was because we reasoned that other deterrents
rendered the adoption of the exclusionary rule unnecessary. This rationale does not apply to violations of the recording rule. The imposition of sanctions against an
individual
officer will not necessarily solve what appears to be a
systemic
problem. Agency policy and operations must change, not simply individual behaviors. Once they are fully aware of the consequences of unexcused violations of
the
Mallott
rule, we are confident that law enforcement agencies will establish effective procedures to implement the rule and provide adequate training for their personnel. Suppression of statements taken in violation of the rule will, therefore, deter continued disregard of its requirements by officers, agencies and courts.
Another purpose is also served by the rule that we now adopt. The integrity of our judicial system is subject to question whenever a court rules on the admissibility of a questionable confession, based solely upon the court’s acceptance of the testimony of an interested party, whether it be the interrogating officer or the defendant. This is especially true when objective evidence of the circumstances surrounding the confession could have been preserved by the mere flip of a switch. Routine and systematic recording of custodial interrogations will provide such evidence, and avoid any suggestion that the court is biased in favor of either party.
Most importantly, an exclusionary rule furthers the protection of individual constitutional rights.
Strong protection is needed to insure that a suspect’s right to counsel, his privilege against self incrimination, and due process guarantees are protected. A confession is generally such conclusive evidence of guilt that a rule of exclusion is justified, when the state, without excuse, fails to preserve evidence of the interchange leading up to the formal statement. This is particularly true when, as in these cases, the defendant may have been deprived of potentially favorable evidence simply because a police officer, in his own discretion, chose to turn the recorder on twenty minutes into the interview rather than at the beginning.
Exclusion is warranted under these circumstances because the arbitrary failure to preserve the entire conversation directly affects a defendant’s ability to present his defense at trial or at a suppression hearing.
Moreover, exclusion of the defendant’s statement is the only remedy which will correct the wrong that has been done and “place the defendant in the same position he or she would have been in had the evidence been preserved and turned over in time for use at trial.”
Harris,
678 P.2d at 413-14 (Singleton, J., concurring and dissenting).
Thus, we conclude that exclusion is the appropriate remedy for an unexcused failure to electronically record an interrogation, when such recording is feasible. A general exclusionary rule is the only remedy that provides crystal clarity to law enforcement agencies, preserves judicial integrity, and adequately protects a suspect’s constitutional rights.
The necessity for
this strong remedy remains, even when we consider society’s interests in crime prevention and the apprehension of criminal offenders. Exclusion of reliable, yet unrecorded, statements will not occur frequently when compliance is widespread.
V. EXCEPTIONS
Despite what we have said thus far, we recognize that nearly every rule must have its exceptions, and that exclusion of a defendant’s statements in certain instances would be wholly unreasonable. A violation of the
Mallott
rule does not, therefore, require exclusion of the defendant’s statements in all cases. Thus, the holding in this case does not bar the admission of statements obtained
before
a violation of the recording rule occurs. Where recording ceases for some impermissible reason, properly recorded statements made prior to the time recording stops may be admitted, even when the failure to record the balance of the interrogation is unexcused, since such prior statements could not be tainted by anything that occurred thereafter. Also, failure to record part of an interrogation does not bar the introduction of a defendant’s recorded statements,
if the unrecorded portion of the interrogation is, by all accounts, innocuous.
In such eases, there is no reason to exclude the defendant’s recorded statements, because no claim of material misconduct will be presented.
See
Rule 47(a), Alaska R.Crim.P. (errors which do not affect substantial rights shall be disregarded). For the same reason, a defendant’s unrecorded statement may be admitted if no testimony is presented that the statement is inaccurate or was obtained improperly, apart from violation of the
Mallott
rule.
REVERSED and REMANDED for further proceedings, with orders that Harris’ and Stephan’s statements be suppressed.
