The Commonwealth of Kentucky appeals from the district court’s granting of a *1127writ of habeas corpus. Petitioner Eric Weir took the stand in his own defense át his murder trial in state court. The prosecutor cross-examined him and made comments to the jury concerning Weir’s silence after he was arrested but before he was given Miranda warnings. The district court concluded that the state had violated Weir’s Fifth Amendment Rights, as outlined in Doyle v. Ohio, 426 U.S. 610, 96 S.Ct. 2240, 49 L.Ed.2d 91 (1976). Accordingly, the district court granted Weir’s petition for a writ of habeas corpus. We agree, and affirm Judge Johnstone’s decision.1
FACTS
Petitioner Eric Weir was convicted in Kentucky state court of first degree manslaughter in the stabbing death of Ronnie Buchanan. The stabbing occurred during a fight in the parking lot of a night club in McCracken County, Kentucky.
While the evidence is not clear as to the cause of the fight, all witnesses agreed that during the course of the fight Buchanan pinned Weir to the ground.2 Suddenly Buchanan jumped to his feet shouting that he had been stabbed. Weir immediately left the scene with his wife, returned momentarily to pick up a friend, and thereafter drove to the home of some friends. He never reported the incident to the police. Subsequently, Weir was apprehended, indicted and brought to trial.
Weir was charged with intentional murder in violation of Kentucky Revised Statute KRS 507.020(l)(a). At trial, he took the stand in his own defense. His testimony on direct examination detailed events inside the bar which led up to the fight and described the circumstances surrounding the stabbing.3 Weir freely admitted stabbing Buchanan, but claimed that he acted in self-defense and that the stabbing was acci*1128dental. This was the first time he had offered an exculpatory story for his actions.
The prosecutor vigorously cross-examined Weir. He inquired into Weir’s assertion that he had been seriously injured. Weir admitted that his injuries had hot required medical attention. The prosecutor then turned to the issue of the knife, asking Weir how he happened to stab Buchanan and how the knife happened to disappear after the stabbing.4 The prosecutor also questioned Weir about his failure to report *1129the incident to the police and disclose his exculpatory story.5 Weir was found guilty of first degree manslaughter and his conviction was affirmed on direct appeal.
Weir then petitioned for a writ of habeas corpus claiming that the prosecutor’s effort to impeach his testimony, by inquiring into and commenting upon his failure to offer the exculpatory story to the police officers at the time of his arrest, violated his constitutional rights. Citing Doyle, supra, and Griffin v. California, 380 U.S. 609, 85 S.Ct. 1229, 14 L.Ed.2d 106 (1965), the district court granted the writ conditioned upon the right of the Commonwealth of Kentucky to retry Weir within 120 days. The Commonwealth has appealed.
I. Preliminary Discussion
We can divide the questions asked by the prosecutor into two basic areas: those concerning pre-arrest silence and flight by the petitioner and those concerning post-arrest silence. Most of the prosecutor’s questions dealt with pre-arrest silence. The prosecutor emphasized that the defendant did not go to the police and was not apprehended for 17 hours after the stabbing. The prosecutor also grilled Weir as to what happened to the murder weapon — the knife with which Weir stabbed the victim.6
Thus far, there was no constitutional impropriety. In Jenkins v. Anderson, 447 U.S. 231, 100 S.Ct. 2124, 65 L.Ed.2d 86 (1980), the Supreme Court ruled that prearrest silence could be used to impeach a defendant who takes the stand. Under Jenkins, much of the prosecutor’s examination of the defendant was proper.
The problem is that the prosecutor did not stop his questioning at petitioner’s prearrest silence. The prosecutor went on to ask Weir why he had not disclosed the knife’s location to the state police when they came to his house to arrest him. The prosecutor also asked Weir why he didn’t try to give an exculpatory explanation to the state police when he was arrested.7
It does not appear from the record that at the time the state police went to Weir’s house and arrested him, that they immediately read Miranda warnings to him. Thus, this case presents the threshold question whether post-arrest silence can be used to impeach a defendant, even though Miranda warnings were not given to him. For reasons discussed below, we conclude that a defendant cannot be so impeached.8
II. Impeachment on the Basis of Post-Arrest Silence
The underlying rationale for limiting impeachment because of silence is simply that “[i]n most circumstances silence is so ambiguous that it is of little probative force.” United States v. Hale, 422 U.S. 171, 176, 95 S.Ct. 2133, 2136, 45 L.Ed.2d 99 (1975). In addition,
*1130evidence at the time of arrest . .. also has a significant potential for prejudice. The danger is that the jury is likely to assign much more weight to the defendant’s previous silence than is warranted. And permitting the defendant to explain the reasons for his silence is unlikely to overcome the strong negative inference that the jury is likely to draw from the fact that the defendant remained silent at the time of his arrest.” Id. at 180, 95 S.Ct. 2138 (citation omitted).
Hale, of course, was decided under the Supreme Court’s supervisory authority over federal proceedings. In Doyle v. Ohio, 426 U.S. 610, 96 S.Ct. 2240, 49 L.Ed.2d 91 (1976) the Court extended the rationale of United States v. Hale to state cases. However, in Doyle, the Court was dealing with a constitutional question and its holding was limited:
We hold that the use for impeachment purposes of petitioners’ silence, at the time of arrest and after receiving Miranda warnings, violated the Due Process Clause of the Fourteenth Amendment.
Doyle, supra, 426 U.S. at 619, 96 S.Ct. at 2245.
A key premise underlying Doyle was the unfairness of giving Miranda warnings to a defendant — which include a statement that the defendant has the right to remain silent — and then impeaching the defendant at trial with that silence. As the Court noted, “[sjilence in the wake of [Miranda] warnings may be nothing more than the arrestee’s exercise of these Miranda rights.” Id. at 617, 96 S.Ct. at 2244.
In a similar vein, in Jenkins v. Anderson, 447 U.S. 231, 100 S.Ct. 2124, 65 L.Ed.2d 86 (1980), the Court held that pre-arrest silence was a proper subject for cross-examination of a suspect at trial. The Court concluded that inquiry into pre-arrest silence was not unfair because “no governmental action induced petitioner to remain silent before arrest.” Jenkins, supra, 100 S.Ct. at 2130.
There is thus a superficial logic to the position that only when a government officer actually reads Miranda warnings to a defendant is it unfair to impeach the defendant with his post-arrest silence. Nonetheless, we conclude that impeachment of a defendant with post-arrest silence is forbidden by the Constitution, regardless of whether Miranda warnings are given. Doyle and Jenkins were decided on a rationale of basic fairness. We think that it is inherently unfair to allow cross-examination concerning post-arrest silence.
First, we believe that post-arrest silence is not probative. In Jenkins, the Supreme Court thought that in many circumstances pre-arrest silence was probative:
Common law traditionally has allowed witnesses to be impeached by their previous failure to state a fact in circumstances in which that fact naturally would have been asserted. 3A Wigmore, Evidence § 1042, at 1056 (Chadbourne rev. 1970). Each jurisdiction may formulate its own rules of evidence to determine when prior silence is so inconsistent with present statements that impeachment by reference to such silence is probative. Id. at 2129.
In the Jenkins case itself, the defendant did not come forward with his claim of self-defense until trial. The state courts could conclude that his failure to come forward earlier was a proper ground for cross-examination.
We think that Jenkins should be limited to instances of pre-arrest silence. Whatever probative value silence has in a pre-arrest context, it has none in a post-arrest situation. An arrest initiates a formal series of proceedings against a defendant. The defendant stands accused of a crime. Under these circumstances, fear and anxiety will lead a defendant — whether innocent or guilty — to silence. As Justice Marshall stated in United States v. Hale, supra :
At the time of arrest and during custodial interrogation, innocent and guilty alike— perhaps particularly the innocent — may find the situation so intimidating that they may choose to stand mute. A variety of reasons may influence that decision. In these often emotional and confusing *1131circumstances, a suspect may not have heard or fully understood the question, or may have felt there was no need to reply. See Traynor, The Devils of Due Process in Criminal Detection, Detention, and Trial, 33 U.Chi.L.Rev. 657, 676 (1966). He may have maintained a silence in response to the hostile and perhaps unfamiliar atmosphere surrounding his detention.
These considerations have little force in a pre-arrest situation, before one stands accused. Arrest changes things. The fact that one has been arrested is significant and should make a difference.
There is a second important reason not to permit post-arrest silence to be used as impeachment. There is widespread knowledge in society that one who is arrested has no obligation to speak to the police and that he is entitled to consult with an attorney. The news media has widely publicized the Miranda case and its formal warnings requirement. Simply stated, many if not most persons under arrest know of their right to remain silent and exercise that right. In fact, many lawyers give out the routine advice to their clients that if the client should be arrested for any reason, the client should say nothing and call the attorney. We do not think that persons who are exercising their right to remain silent should be penalized for it.
Jenkins and Doyle thought it unfair to impeach by use of silence where “governmental. action induced petitioner to remain silent.” Jenkins, supra, 100 S.Ct. at 2130. We think that an arrest, by itself, is governmental action which implicitly induces a defendant to remain silent. When one combines a suspect’s fears and anxieties upon arrest with widespread knowledge of one’s right to remain silent, the result is often just that — silence. Given these realities, we think it is fundamentally unfair to allow impeachment through the use of any post-arrest silence.
The facts of this case illustrate this unfairness. Petitioner Weir got into a fight with Ronald Buchanan and stabbed Buchanan to death during the fight. Petitioner fled. After some delay, the police came to his house and arrested him. The police also searched the house. When repeatedly questioned at trial as to why he didn’t exculpate himself to the police, petitioner stated that “I didn’t feel I ought to tell them anything.”
The petitioner was absolutely correct. His best course of action was to consult with counsel and remain silent until then. He generally knew this. It was clear that petitioner would face legal problems as a result of the fight. The nature and extent of these difficulties, however, was unclear. Petitioner’s silence was thus not probative of guilt. It was unfairly prejudicial for the prosecutor to pursue this matter at trial.9
*1132III. Some Practical Considerations
If we were to limit Doyle to instances where the police actually read Miranda warnings to a defendant, many practical problems arise.
First, it would penalize the knowledgeable defendant. As indicated above, many persons are aware of their rights and do not need to be read Miranda warnings. We see no logic in allowing impeachment of the defendant who tells the police that he is aware of his rights and wants to talk to his attorney, but not allowing impeachment if the police actually read the Miranda warnings.
Second, such a position would discourage the reading of Miranda warnings. By its terms, Miranda applies to “in custody interrogation.” Miranda v. Arizona, 384 U.S. 436, 468, 86 S.Ct. 1602, 1624, 16 L.Ed.2d 694 (1966). This means post-arrest interrogation.10 Most police departments routinely have officers read Miranda warnings at the time of arrest. This helps prevent difficulties which may develop if the officer and the defendant converse on the way to the police station. See Rhode Island v. Innis, 446 U.S. 291, 100 S.Ct. 1682, 64 L.Ed.2d 297 (1980); Brewer v. Williams, 430 U.S. 387, 97 S.Ct. 1232, 51 L.Ed.2d 424 (1977). More important, this procedure ensures that the defendant is aware of his rights from the inception of the arrest. However, there is no requirement that the Miranda warnings be read at the time of arrest. As the Court noted in Rhode Island v. Innis, supra, 446 U.S. at 300, 100 S.Ct. at 1689, “the special procedural safeguards outlined in Miranda are required not where a suspect is simply taken into custody, but rather where a suspect in custody is subjected to interrogation.” 11
Thus, the police have some discretion in deciding when to read Miranda warnings. If we limited Doyle v. Ohio to instances where the police actually read the warnings, they could eviscerate Doyle through the simple expedient of not reading Miranda warnings at the time of arrest. The police could simply arrest a suspect and be careful not to interrogate him for 15-20 minutes. If the police wanted to question the suspect, they could then read the Miranda warnings. If the suspect had remained silent for those 15 — 20 minutes, that silence could be used for impeachment at trial. Such a result would be illogical.
IV. Harmless Error
The state has a good argument that the improper use of post-arrest silence in this case was harmless beyond a reasonable doubt. The unlawful prosecutorial inquiry into Weir’s post-arrest silence was not prolonged or emphasized. In addition, the questions paralleled questions the prosecutor properly asked about Weir’s pre-arrest silence. The issue of harmless error in Doyle v. Ohio situations has come up often. We refer the reader to Williams v. Zahradnick, 632 F.2d 353, 360-65 (4th Cir. 1980) (citing numerous cases) for an extensive discussion of this question.
In this case, we conclude that the error was not harmless beyond a reasonable doubt. We are dealing with a fight which *1133ended in a stabbing. As can be expected, the witness’ testimony is conflicting. The jury convicted Weir not of murder, but of first degree manslaughter.
Courts should be cautious in applying the harmless error doctrine. See Eberhardt v. Bordenkircher, 605 F.2d 275, 278-80 (6th Cir. 1979). In this case, although the error was not pronounced, it may well have affected the jury’s decision. The circumstances surrounding the fight and subsequent stabbing were very muddled at trial. A jury plays a particularly important fact-finding role in cases like this. A jury should have an opportunity to determine Weir’s culpability without the taint of constitutional error. We conclude that the error was not harmless beyond a reasonable doubt.
V. Conclusion
The judgment of the district court is affirmed.
