The First (?) Post-Heller Case Holding a Gun Control Law Unconstitutional:
That’s U.S. v. Arzberger. The gun control law is the part of 18 U.S.C. § 3142(c)(1)(B) that requires that when someone is charged with possessing child pornography (among other crimes) and is freed on bail, he be ordered not to possess any firearm.
Judge Francis decided that constitutional rights mean something after all.
