Say that I am standing on the Illinois side of the border.  There is another man standing a little way away from me, but on the Wisconsin side of the border.  I shoot that man dead.  Who has jurisdiction?

A murder definitely occurred, but on which side of the border did the actual physical crime occur?  Is the act of firing the gun with the crime or is the result of the act the crime?  Can you separate the two?    Or is this one of those jurisdictional nightmare situations where you have two district attorneys fighting for the prestige of getting a conviction for an unusual crime and all the press that goes with it?  I certainly couldn’t be tried for murder in both states because that would violate double jeopardy.

Never a lawyer when you need one.
