The News Scan notes today's decision in United States v. Abramski, in which the Court affirmed, 5-4, the conviction of a straw purchaser for lying about the actual intended owner of the gun.
There is a strong dissent by Justice Scalia, relying in part on the rule of lenity, which, the Justice maintains, might as well be explicitly tossed overboard if it is not to be applied in favor of Mr. Abramski.
There is something of a battle of the footnotes about this question, as pointed out in Prof. Josh Blackman's blog entry. Although I most often agree with Justice Scalia and his three dissenting colleagues, in this instance I thought Justice Kagan got the better of the argument.
I would add only one thing. If you don't want to get prosecuted for lying, don't lie. It's not that hard.
