(dissenting):

I must respectfully dissent.

This is an unusual case. A divinity student is charged with assaulting a deputy U. S. Marshal. He admits kicking the Marshal. His defense was twofold. First he claimed he did not know the person kicked was a U. S. Marshal. This was resolved against him by the trial court and by the majority here in its correct holding that knowledge of the official status of the victim of the assault is not an element of the offense under 18 U.S.C. § 111 .

Second, his factual defense was that he went to the aid of a person he believed was being assaulted. He received complete and favorable instructions to the jury on this issue and they found him guilty.

The majority was compelled to hold that official status of the victim was not an element of the offense by our decision in McEwen v. United States, 390 F.2d 47 . They now reach for other grounds to reverse the conviction. The majority opinion bases its reversal on two supposed errors which cumulatively, it is said, require reversal.

I.

The first error found was the rejection of the offer of proof of instructions to the United States Marshals not to arrest in certain Selective Service cases. 1 The majority opinion does not so state but gives the impression that this was an issue taken from the jury. It was instead an issue of law decided by the trial court. Appellant’s counsel specifically agreed that the issue of whether the deputy Marshal was “engaged * * * in his official duties” ( 18 U.S.C. § 111 ), was not a question for the jury. (Rep.Tr. 308-9).

The court considered counsel’s offer of proof and stated he took judicial notice of the courtroom remarks of U. S. Attorney Cecil Poole in another proceeding. Far from showing any express instructions to Ü. S. Marshals as to arrests in Selective Service cases, Poole’s remarks rather refer to matters of pros-ecutive policy. But at best the offer of proof showed “* * * a national policy of the Department of Justice that the FBI and United States Marshals would not either question people about possession of draft cards (looking toward arrest or prosecution therefor) or arrest for nonpossession * * *” of draft cards. “The policy * * * was communicated to the United States Marshals, as their binding instructions, by the Department of Justice.” (Clk. Tr. 3-4).

From the showing made, the policy was at best a nebulous one. The court stated “I don’t know of any regulations that have been cited that could have the standing of law in respect to the enforcement of the Selective Service Act by the Marshals.” Appellant’s attorney then conceded “I don’t know if they exist. I believe they probably don’t exist.” (Rep.Tr. 314).

The majority cite 28 U.S.C. § 569 (c) vesting authority in the Attorney General to “supervise and direct United States marshals in the performance of public duties * * *" and 28 C.F.R. § 0.5 (a) to the same effect. The majority then states “* * * [W]e have no doubt that under this broad grant of authority the Attorney General could properly limit the occasions upon which United States marshals and their deputies might exercise the general statutory

*899 power to make arrests, ” [Emphasis added]

We have no doubt either. But appellant’s counsel admitted no such regulatory limitations existed; and even if they existed, the majority do not tell us how a violation of such a supposed regulation would constitute a defense in a criminal action.

It is conceded that the statute, 18 U.S.C. § 3053 permits a Marshal to make an arrest without a warrant for an offense committed in his presence. Although the Marshal may have violated instructions, he had power to make an arrest, and his acts were merely subject .to departmental discipline. The majority, in substance, read the instructions as amending the statute passed by Congress. If the Marshal had authority to make the arrest under the statute, the fact that he violated his instructions from the department could not possibly be a defense.

It was not necessary to determine whether the arrest of Jones (to whose aid appellant came) was technically legal. The cases cited by the Government give solid support to the statement that good faith action, under color of authority by a federal officer is sufficient to satisfy the “engaged in his official duties” standard. United States v. Heli-czer (2 Cir.1967), 373 F.2d 241 , 245 states the rule. “ ‘Engaged in * * * performance of official duties’ is simply acting within the scope of what the agent is employed to do. The test is whether the agent is acting within that compass or is engaging in a personal frolic of his own. It can not be said that an agent who has made an arrest loses his official capacity if the arrest is subsequently adjudged to be unlawful.” Heliczer concerned a prosecution for attack on a federal narcotics agent under 18 U.S.C. § 111 . Defendants claimed that the arrest by the agent was unlawful as outside the scope of official duties. The court rejected the argument.

The other cited cases similarly involve convictions for attacking federal officials. Efforts to categorize the official as working outside the scope of his authority failed in each instance. Walks on Top v. United States (9 Cir.1967), 372 F.2d 422 , cert. denied 389 U.S. 879 , 88 S.Ct. 109 , 19 L.Ed.2d 170 (1967) held a Bureau of Indian Affairs agent was in the scope of official duty where he was working with state law enforcement officials after being deputized as a state official.

Arwood v. United States (6 Cir. 1943), 134 F.2d 1007 , cert. denied 319 U.S. 776 , 63 S.Ct. 1436 , 87 L.Ed. 1722 (1943) rejected a claim that an Alcohol Tax Unit investigator’s participation in an illegal search might remove him from the protection of the federal “scope of duty” statute. The court held it need not determine the validity of the search. “The fact remains that the entry of the deceased [federal official] into the house or upon the premises and any search made there was in the course of the investigation and germane to the performance of the duties of the officers while bona fide acting under the color of authority.” (134 F.2d p. 1011).

Finally Hodgdon v. United States (8 Cir.1966), 365 F.2d 679 , rejected a claim that an arrest warrant was invalid and hence that a federal marshal seeking to enforce it was acting outside his duties. Although the court found the warrant proper, it noted: “We believe it is part of the official duties of a marshal, in criminal as well as civil cases, to execute all warrants which reasonably appear to be valid. At any rate, no person should be entitled to resist with deadly force a marshal operating under color of authority, even though it is later found that no actual authority existed.” (p. 685). See also Amaya v. United States (9 Cir.1957), 247 F.2d 947 .

More startling and erroneous is the narrow scope given by the majority to the deputy Marshal’s duties on the day in question. They seem to assume that the only duty he was engaged in was the arrest of Jones referred to in note 1. Deputy Marshal St.Germain testified he was on duty as a deputy Marshal on the day in question along with other depu *900 ties; that he was instructed to be at the Center to protect government property; that in the course of his duties he went to Armed Forces Induction Center at 4:45 A.M. and was in the building until 8:15 A.M.; that he at first couldn’t get in because the area was crowded with people; that Chief Deputy Marshal Blazzard was inside and couldn’t get out; that there was a sit-in in front of each doorway; that police came to the 15th Street doorway and apparently opened the way; that the incident with Jones happened shortly thereafter. (Rep.Tr. 140-144).

We can take judicial notice that the Induction Center was maintained by the government so that registrants and prospective inductees could report thereto, and that the government had an interest in protecting the Center, keeping it open and maintaining access to it. Thus St. Germain was on duty in attempting to maintain order and protect government property. Even if he had no power to arrest, he was engaged in other official duties at the same time. He thus was “engaged in * * * the performance of his official duties.”

II.

The opinion, secondly, finds error in the limitation of the right to cross-examine the deputy Marshal. The opening questions by counsel for the appellant were general questions, directed as to whether or not the deputy Marshal had any bias or prejudice, or any feelings of opposition, anger or bitterness towards persons who participated in anti-draft and anti-war demonstrations. The government’s objection was sustained.

We think the majority was correct in holding that the trial court sustained the objection to 'the general line of questions. All the discussion between court and counsel centered on the question of bias or prejudice toward the Vietnam war demonstrators. When finally the court stated he understood that counsel’s questions were “not as to whether or not he (the deputy Marshal) had a bias toward this individual defendant.’-’ Counsel replied “That’s right,” and then added “And unless he (the deputy Marshal) attached it to him (the appellant) because he is in that grouping.” (Rep. Tr. 163).

But although the objection was sustained to the line of questions as to general bias against the Vietnam war demonstrators, the trial court invited specific questions. But counsel for appellant did not follow up with particular questions as to any bias or prejudice of the deputy Marshal against the appellant himself. The attorney for appellant should have framed particular questions as to the deputy Marshal’s supposed prejudice toward the appellant, and the appellant’s connection with the group of demonstrators.

The sustaining of an objection on cross-examination to a question framed in general terms, like the general objection to a question, will ordinarily not constitute grounds for an appeal. The duty lies with the party propounding the question to specify with his questions the issue he desires to raise and to obtain a ruling on the specific questions and the objection thereto.

The majority states that a defendant is entitled to a reasonable opportunity to cross-examine witnesses as to the existence of prejudice against a group of which the defendant is a part. The opinion relies on three state court cases decided in 1949, 1899, and 1855, and dictum in a 1902 federal district court case to support this position. In the 1949 case, Jacek v. Bacote, 135 Conn. 702 , 68 A.2d 144 , the trial court allowed the question as to class prejudice. The reviewing court found the action “was not improper.” In the 1899 ease, Magness v. State, 67 Ark. 594 , 50 S.W. 554 , 59 S.W. 529 , a witness’ prior hostile statement, excluded by the trial court, was clearly directed to the individual defendant. Only in People v. Christie, 2 Abb. Pr. 256 , 2 Park.Cr.R. 579 (N.Y.S.Ct. 1st D. 1855) was the appellate court faced with a factual record similar to the present case — -a refusal by the trial court to allow questions about a witness’ *901 bias against a general class rather than a particular individual. We would not quarrel with the majority’s conclusion that a trial judge may in his discretion allow questions as to bias against a class. However, a requirement that he accept such general questions misreads sparse precedent and places an undesirable restraint on the judge’s control of trial proceedings.

If it is suggested that the paucity of direct authority in this area is due to the fact that a trial judge rarely denies cross-examination directed to subject matter of the kind involved here, a more plausible explanation, based on the writer’s experience of 18 years on a trial bench, is that counsel will usually re-frame his question to speak to bias against the individual.

The cases are legion that the scope of cross-examination is largely within the discretion of the trial court and its ruling, absent a showing of abuse of discretion, will not be reversed. Ford v. United States (5 Cir.1956), 233 F.2d 56, 61 , cert. denied 352 U.S. 833 , 77 S.Ct. 49 , 1 L.Ed.2d 53 ; Mims v. United States (9 Cir.1958), 254 F.2d 654, 659 ; Sykes v. United States (5 Cir.1966), 373 F.2d 607, 611 , cert. denied (1967) 386 U.S. 977 , 87 S.Ct. 1172 , 18 L.Ed.2d 138 ; Abeyta v. United States (10 Cir.1966), 368 F.2d 544, 545 .

Sykes and Abeyta, supra, were stronger cases for allowing the question on cross-examination than our case. In each the discretion of the trial court was upheld in sustaining the objection. In Sykes a witness’ testimony helped place defendant at the scene of a post office robbery. On cross-examination it was revealed that the witness had had a lovers quarrel with the co-defendant. The court refused to allow an inquiry as to whether the witness had assaulted the co-defendant. On appeal the circuit court surmised that the trial judge had felt this evidence was extrinsic to the case and excludable in his discretion. In Abeyta, a detective was apparently the key witness in a marihuana conviction. Defendant attempted to show the witness had been about to resign from a previous law enforcement position for going “a little too far in his work.” The circuit upheld the discretion of the trial court in excluding the evidence.

More important the question of the deputy Marshal bias was not germane to any material issue. There was never any issue as to whether appellant kicked the deputy Marshal. His own counsel assumed the kicking in his questions to appellant, when he testified in his own defense. Appellant’s testimony admitted the kicking. 2 St.Germain and others testified appellant kicked him.

The majority does not tell us just how cross-examination as to the deputy Marshal’s bias toward Vietnam war demonstrators would assist the defense on this state of the record. The deputy Marshal testified generally to what occurred on December 18, 1968. 3 But the crucial testimony was that appellant kicked him. Appellant’s main defense was his *902 claimed right to go to the defense of a person being assaulted. The court so instructed. Nothing in St.Germain’s testimony affected this defense. In fact St.Germain related how he and the guard were holding Jones on the ground and attempting to hand cuff him at the time appellant intervened.

It is true that St.Germain testified that he twice announced he and the others were Federal Marshals. But the issue of appellant’s knowledge that St. Germain was a deputy Marshal was held by the trial court and the majority here to be a matter of law and not of fact and not an element of the offense that the government was required to prove.

We thus have a case where the act in question, the kicking, was testified to by the deputy Marshal and admitted by appellant and where the deputy Marshal’s testimony of his encounter with Jones laid the basis for appellant’s only real factual defense, viz. that he had gone to the aid of a person being assaulted. And yet the majority holds the sustaining of the objection as to the deputy Marshal’s bias against Vietnam war demonstrators, was reversible error.

The case was ably and patiently tried by the judge presiding. Despite a great number of contentions and objections, constitutional and otherwise, all untenable, the trial court afforded the appellant a fair trial and the jury convicted him.

The opinion of the majority will cause only mischief. Trial lawyers will be confused. District Judges will have the opinion cited to them as permitting the most general of questions as proper cross-examination, and the judges will be reluctant to limit cross and require questions as to specific matters. Cases will be delayed by unwarranted cross-examination. It is submitted the majority is in error in its holding, that appellant was not prejudiced on the record here and the decision will be an added obstacle to the administration of justice in the trial courts.

The judgment should be Affirmed.

. St. Germain, the deputy Marshal assaulted, had questioned one Jones, a demonstrator, about his failure to have a draft card in his possession. He arrested Jones and was attempting to put hand cuffs on Jones when appellant kicked him.

. Appellant took the witness stand and at no time denied that he kicked or kneed deputy Marshal St. Germain. The following is from his direct examination by his own counsel:

. Summary of the testimony of deputy Marshal St. Germain.

Deputy Marshal St. Germain testified that he had been in the Marine Corps *902 for 20 years and after his retirement had become a deputy Marshal on August 19, 1965. That he, other deputy Marshals and Foreman a guard, had gone to the Armed Forces Induction Center, Oakland on December 18, 1968. He saw the demonstrators in front of each of the three doors to the Center and subsequently had a conversation with Jones.

He told Jones he was a Marshal, showed him his credentials; asked if Jones had any identification, he said he did not; asked if he had a draft registration card and he said no; asked if he was of draft age and he said yes. He then told Jones he was under arrest. He then related that Jones threw his hands up and said, “Oh no” and ran. The guard Foreman grabbed Jones and Jones kneed Foreman. Then St. Ger-main grabbed Jones and forced him to the ground; he attempted to put hand cuffs on Jones and saw a group of people coming across the street. He told them that they were Federal Marshals and the man was under arrest and to “leave us alone” and that he was then kicked by the appellant and that appellant ran back into the crowd. That St. Germain went back to where Jones was and appellant came at him again.. This time he took his black-jack out and told appellant they were Federal Marshals and to leave them alone; that he swung the black-jack and kept swinging it but did not hit anyone; that his boss (Chief Deputy Marshal Blazzard) subsequently apprehended Kartman.
