Man fires a gun across state lines....

Yes. Heath v. Alabama, 474 U.S. 82, 106 S.Ct. 433, 88 L.Ed.2d 387 (1985).

Heath had two men kill his wife for $2000. He left his residence in Alabama, met the two men in Georgia, and led them back to Alabama. His wife was later found dead of a gunshot wound to the head in Georgia. Heath pleaded guilty to malice murder in Gerogia in exchange for life imprisonment. Later, he was tried for murder during a kidnapping in Alabama and sentenced to death. He appealed to the U.S. Supreme Court, arguing that his conviction in Georgia barred his prosecution in Alabama for the same conduct, due to the double jeopardy clause.

The Supreme Court rejected his argument an upheld the Alabama conviction, saying the following: “In applying the dual sovereignty doctrine, the crucial determination is whether the two entities that seek successfully to prosecute a defendant for the same course of conduct can be termed separate sovereigns. This determination turns on whether the two entities draw their authority to punish the offender from distinct sources of power…The States are no less sovereign with respect to each other than they are with respect to the Federal Government. Their powers to undertake criminal prosecutions derive from separate and independent sources of power and authority originally belonging to them before admission to the Union and reserved to them by the Tenth Amendment.”

[hijack] This happened to me as well, in a shopping centre parking lot. Luckily, it was a very slow-motion impact, so the only damage was a slight dent in the plastic trim strip on the driver’s door. My initial reaction was to suspect a stolen car abandoned by joy-riders or drunk driver (I was parked between the liquor store and the beer store) and call the police. When the police and, eventually, the driver showed up, the real cause was determined to be a slight slope in the parking lot and a car left in gear by the driver when she parked. No charges as there was no damage, but one of the cops remarked privately that there should be a charge of “driving without a brain”. I agreed - the driver seemed totally unable to comprehend how her car had moved from where she left it, even after the cops had explained it to her twice. [/hijack]

Thanks for the cite, Pravnik. I know what the Supreme Court says is law, but it still seems like double jeopardy to me, I mean they once said slavery was legal also!
