Emmеtt Eugene Cloud, Jr. was arrested in the steam room of a Dallas health studio on a charge of public lewdness and convicted by a Texas jury. The prosecution’s case rested entirely on the testimony of a single witness, the arresting officer. Cloud’s petition for habeas corpus asserts that the trial judge’s refusal to permit cross-exаmination of the officer concerning a prior incident that had resulted in the officer’s suspension violated Cloud’s sixth amendment right to confront the witnesses against him. Because the petitioner has no constitutional right to impeach the general credibility of a witness with evidence of prior bad acts, we AFFIRM the District Court’s denial of the writ.
Between the time of Cloud’s arrest and trial, the arresting officer filed a false report in an unrelated “vice undercover operation.” The officer was suspended and later reassigned to the traffic patrol, but no criminal charges were brought. In the absence of a criminal conviction, the trial judge refused to permit cross-exаmination into the incident. Defense counsel objected on the sole ground that his client had a right to show that the officer had a propensity to be “untruthful.” There was no suggestion either before the state court or this court that cross-examination would show any “biases, prejudices, or ulterior motives” on the part of the officеr,
Davis v. Alaska,
*744
While the Federal Rules of Evidence permit a criminal dеfendant, at the discretion of the court, to impeach the credibility of a hostile witness with evidence of prior instances of dishonesty (see Fed.R.Evid. 608),. we find no authority fоr the proposition that a defendant has a constitutional right to attempt such impeachment. In
Davis v. Alaska, supra,
the Supreme Court found a sixth amendment violation in a state judge’s refusal to permit cross-examination into the partiality of a key prosecution witness. The witness had been adjudicated a juvenile delinquent; his probationary status аt the time of Davis’ trial might have motivated the witness to identify Davis as the culprit in order to shift suspicion from himself and prevent possible revocation of probation. Nоting that “the exposure of a witness’ motivation in testifying is a proper and important function of the constitutionally protected right of cross-examination,”

Under
Davis,
cross-examination must be permitted into any incentive the witness may have to falsify his testimony. Here, the petitioner has failed to advance such an incentivе. Instead, the petitioner argues that the fact that the witness lied before may be introduced to show that the witness is lying now. While

mentions the traditional importance of аllowing the cross-examiner to discredit a hostile witness,

Notes
. The following colloquy took place between the trial judge аnd defense counsel after a proffer of cross-examination on the suspension:
THE COURT: Just in order to let the record reflect what we are doing, I will now hear the Dеfendant’s argument for why they think that this testimony is admissible in view of the State’s Motion in Limini. I would like for you to site (sic) your authorities which I instructed you this morning to have ready to show that you can impeach a witness by something other than a conviction for an offense. When you site me that authority, I am ready to hear your argument.
[Defense Counsel]: Your Honоr, the Defendant has no authority for such proposition. This witness’ credibility is in question here and if he has been discipline (sic) within his own department for being untruthful, we have a right to put thаt in evidence here.
THE COURT: You have no authority for that, this is a case of first impression as far as you are concerned.
[Defense counsel]: We are testing this witness’ credibility and we have a right to go into it.
THE COURT: Counsel, this Court would have to assume that if that were the law, that anybody could call any witness’ wife or spouse up here, and I don’t think there is anybody in the world who hasn’t lied to your spouse at one time or another. Unless you get into some matter that shows some kind of a conviction, the Court will sustain the objection and rule that the matter is not admissible in front of the jury. Now 1 thought I made that very clear this morning, that if you had any authority, I want to hear it now. That is not to say that before this trial is ovеr with, if you show me some authority for your position, that I won’t change *744 my ruling and then Jet you go into it, but until you show me some authority the Court holds that the mere fact that someone mаy have made some false statement to someone in the past, which has not resulted in a final conviction, it is not admissible in this State as far as I have been able to determine. Does anybody want to ask any further questions of this witness before I bring the jury back in?
[Defense counsel]: Please note our exception. (Emphasis Supplied).
