Woman is convicted of assault for slapping a fellow passenger on flight from Minneapolis to Los Angeles. (She’s fined $760.) Ninth Circuit (creating a circuit split): Conviction reversed. The trial was held in federal district court in Los Angeles, but the assault happened before the plane reached that district’s airspace. Dissent: Asking victims to pinpoint and the gov’t to prove the precise moment an assault took place will make prosecutions (of crimes much more serious than this one) on board aircraft well-nigh impossible.
