In U.S. v. Tagg, No 08-16860 (June 30, 2009), the Court affirmed the conviction of a defendant charged with aiding and abetting in the possession of a pipe-bomb.
The Court rejected Tagg’s challenge to the sufficiency of the evidence, pointing out that his conduct in helping persons purchase gunpowder, watching them build pipe bombs in his garage, and telling them to go light the bombs somewhere else, sufficed.
The Court also rejected Tagg’s argument that the Second Amendment protected his activity. Unlike handguns "pipe bombs are not typically possessed by law-abiding citizens for lawful purposes."
