box and volunteered to open it. In the box were two sticks of dynamite taped together, a detonator cap attached to one stick, and three or four coils of fuse. The officer arrested Green and took him to the Coal-ville County jail. The local justice of the peace fixed bail for Green at $10,000. Green called Hopkinson and told him that he, Green, was in jail for speeding.
On the next day Hopkinson and Hickey came to Utah and deposited $2,000 cash bail for Green. Subsequently Green pleaded guilty to possession of a concealed weapon and paid, out of the bail deposit, a $250 fine.
The government traced the dynamite to the Schreiner ranch from which it was stolen, together with some fuse and detonators, sometime between August and October 1976. Government witness Stoddard testified that in late August Hickey and Jamie Hysell came to her home in Mountain View, Wyoming with some dynamite, fuse and blasting caps. Both she and Green told about later experiments and pranks with dynamite.
The participants in the various events detailed in the record resided in isolated communities of an area in southwestern Wyoming known as Bridger Valley. The population centers are five to ten miles apart. Hopkinson’s family had lived in Bridger Valley for many years and was engaged in ranching and construction. Hopkinson managed a store in Urie, Wyoming. Government witnesses Lacey and Green testified that Hopkinson claimed that one Mariscal, of Phoenix, Arizona, owed him, Hopkinson, money. Green said that at the request of Hopkinson he telephoned the Mariscal residence in Phoenix to demand payment. He and Hopkinson discussed means of intimidating Mariscal to secure payment.
Hopkinson, Hickey and Green were present when a dynamite bomb was made at Hopkinson’s residence. Hopkinson asked Green to take the bomb to Phoenix and blow up Mariscal’s car. Green was to receive $2,000 from the money which Hopkin-son hoped to get from Mariscal. The plan failed because of the speeding arrest of Green. The dynamite in the bomb was from that which had been stolen from the Schreiner ranch. Two government experts identified a finger print on the box containing the bomb as that of Hopkinson. Ink marks on the box were identified by experts as the same as that of a pen used by a live-in girl friend of Hopkinson. Hopkin-son did not testify at the trial.
The record discloses an aura of violence pervading the Wyoming area where various events related to the defendants and the witnesses. A bomb explosion, which killed three persons, and a separate murder had occurred. Considerable publicity had resulted from these events. The trial court, and the lawyers, were concerned with the possibility of prejudice to the defendants by any reference to the violence. Extreme caution was taken to protect the parties from any prejudice which might arise from acts unconnected with the specific offenses for which the defendants were tried.
Hopkinson claims that the trial court im-permissibly limited the scope of voir dire examination of prospective jurors. In this regard consideration must be given to the mentioned background of violence and to the defense claim that government witness Green was not worthy of belief. The spe-. cial prosecutor in the case was an associate in law practice with a Wyoming lawyer who was engaged as a special prosecutor in a state case arising from the violence unconnected with the instant case.
The boundaries of voir dire are within the discretion of the trial court. Rule 24, F.R.Crim.P. and
United States v. Polk, 10 Cir., 550 F.2d 1265, 1267, cert. denied
434 U.S. 838, 98 S.Ct. 129, 54 L.Ed.2d 100. This discretion will not be disturbed unless the voir dire was inadequate to test properly the qualifications of the prospective jurors. The court need not ask requested questions which are argumentative or cumulative.
United States v. Evans, 10 Cir., 542 F.2d 805, 813, cert. denied 429 U.S. 1101, 97 S.Ct. 1124, 51 L.Ed.2d 550. The case at bar is devoid of any racial overtones.
