The way it stands as is, it is not illegal for the same crime to be prosecuted twice, so long as it is in two different jurisdictions. For instance, if someone in Texas commits one crime, and that crime violates both federal and Texas' state statutes, that person can be tried twice (once in each jurisdiction) for that crime.
What are everyone's thoughts on this? Also, how often does this actually happen?
I find it quite interesting, but I'm sure there must be some justification for it.
