We need not consider the allegedly erroneous rulings; they do not affect the conviction on the possession counts. United States v. Jack, 1971, 9 Cir., 439 F.2d 879. Hatfield presents a multitude of arguments, the most serious of which concerns an interpretation of the National Firearms Act. He argues that he could not "possess a firearm which is not registered to him in the National Firearms Registration and Transfer Record," § 5861(d), without first having had the firearm "transferred" to him as that term is defined in the Act, which defines a "transfer" as including "selling, assigning, pledging, leasing, loaning, giving away, or otherwise disposing of."
There was shown no prejudice from the delay between the offenses and arrest, and we dismiss this assignment of error under Wilson v. United States, 409 F.2d 184 (9th Cir. 1969), cert. denied, 395 U.S. 983, 89 S.Ct. 2146, 23 L. Ed.2d 771 (1969), in which there had been a seven-month delay. The remaining issue need not be considered, appellant having received concurrent sentences on all counts. United States v. Lucero, 443 F.2d 64 (9th Cir. 1971); United States v. Jack, 439 F.2d 879 (9th Cir. 1971). The decision of the district court is affirmed and the mandate will issue forthwith.
Inasmuch as the sentences were for the same period of time and made to run concurrently, we need sustain the validity of only one conviction to affirm the judgment. United States v. Jack, 439 F.2d 879 (9th Cir. 1971); United States v. McKinney, 433 F.2d 921 (9th Cir. 1970); Johnson v. United States, 427 F.2d 537 (9th Cir. 1970); and United States v. Wong, 425 F.2d 1077 (9th Cir. 1970). Consequently, we shall examine only the judgment of conviction on the third count.
Also, the sentences were concurrent. Thus, we need not necessarily find more than one robbery count good as to each defendant-appellant. See Benton v. Maryland (1969), 395 U.S. 784, 89 S.Ct. 2056, 23 L.Ed.2d 707; Hirabayashi v. United States, (1943) 320 U.S. 81, 63 S. Ct. 1375, 87 L.Ed. 1774; United States v. Jack, 439 F.2d 879 (9th Cir., Feb. 24, 1971); United States v. McKinney, 433 F.2d 921 (9th Cir., Nov. 16, 1970). We affirm both judgments of conviction.
In any event under the concurrent sentence doctrine of Hirabayashi v. United States, (1943) 320 U.S. 81, 105, 63 S.Ct. 1375, 87 L.Ed. 1774, as a matter of judicial convenience, we are not required to examine the validity of more than one of the counts. Accord, United States v. Jack, (9 Cir. 1971), 439 F.2d 879. V. The Sale of Cocaine Charged in Count I Was a Completed Sale.
The concurrent sentences rule makes examination of this assignment of error unnecessary. Benton v. Maryland, 395 U.S. 784, 89 S.Ct. 2056, 23 L. Ed.2d 707 (1969); Hirabayashi v. United States, 320 U.S. 81, 105, 63 S.Ct. 1375, 87 L.Ed. 1774 (1943); United States v. Jack, 439 F.2d 879 (9th Cir. 1971). There is no merit to the contention that the introduction of this evidence "contaminated" the entire trial.
