By permission of the court, Nestor Martinez makes a post-confinement appeal challenging a judgment entered against him on January 9, 1967, in the United States District Court for the Southern District of New York (Lloyd F. MacMahon, Judge) after trial to a jury, convicting him on two counts of *81 selling marijuana, in violation of 21 U. S.C. § 176a, on one count of assaulting with a deadly weapon a federal agent engaged in the performance of his official duties, in violation of 18 U.S.C. §§ 111, 1114, and on one count of assaulting four agents in the performance of their duties, also in violation of . 18 U.S. C. §§ 111, 1114. Martinez was sentenced to six years imprisonment on counts one through three and to three years on count four, all to run concurrently. He has served his sentence and is now released on parole.
Martinez’ challenge to the convictions on the selling counts is based on the Supreme Court’s decision in Leary v. United States,
The essence of Martinez’ claim is that the federal undercover agents who arrested him after he transferred to them a suitcase full of marihuana had no probable cause to arrest and that he therefore had a right to resist with reasonable force. He claims that the subsequently declared retroactive unconstitutionality of § 176a in addition to the agents’ admitted lack of knowledge of importation left them without any information on one element of the crime, and that his flight and aiming of a gun at an agent were reasonable means of repelling an unlawful arrest. We need not decide whether
Liguori, supra,
operates to vitiate probable cause for arrests made before the
Leary
decision, and valid when made (but cf. United States v. Beyer,
In ascertaining whether there was probable cause for the arrest, we rely on an objective rather than a subjective standard and look to the facts known to the agents at the'time of arrest rather than to their characterization or stated basis for their behavior. “ . . . the test for probable cause does not involve speculation about the outcome of a trial on the merits [of the charge on which defendant is told he is being arrested], but rather upon an assessment of whether the knowledge of the arresting officer at the time of arrest would be sufficient to warrant a prudent man in believing that the person arrested had committed or was committing
an offense.”
United States v. Atkinson,
This is not to say that a court will indulge in “ex post facto extrapolations of all crimes that might have been charged on a given set of facts at the moment of arrest . . . [for] such an exercise might permit an arrest that was a sham or fraud at the outset, really unrelated to the crime for which probable cause to arrest was actually present
*82
to be retroactively validated.”
In the present case, the crime on which Martinez was arrested and those for which the agents had probable cause were closely related, and no one has questioned the propriety of their motives in making the arrest. Therefore, Martinez had no right to resist this lawful arrest by federal officers, whether or not they were known to him as such. United States v. Ulan,
Even were the arrest without probable cause, Martinez was not justified in responding with the excessive force he displayed. An agent, even if effecting an arrest without probable cause, is still engaged in the performance of his official duties, provided he is not on a “frolic of his own,” and is protected from interference or assault. United States v. Beyer,
The only way in which Martinez could avoid the impact of Beyer would be to show that he did not know the identity of the agents when he assaulted them and that he thus fell into that class of cases in which the use of reasonable force in resisting unlawful arrest is justified. * Although we need not decide this issue, we note that although the question of his knowledge of the identity of the agents was not submitted to the jury, there was a substantial *83 amount of evidence tending to show that when he assaulted the agents he must have known of their official status. In any case, finding his arrest to have been valid and his resistance and assault on the agents unjustified and unlawful, we affirm the convictions on counts three and four.
