The 6th AM, in part:
Amendment VI
In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the state and district wherein the crime shall have been committed, which district shall have been previously ascertained by law...
If you committed a crime in A, then A should prosecute, not B, unless, as I stated, it was a "continuing" crime or such, and several jurisdictions were involved??
I don't know why there is a conflict of jurisdictions here. If one charge is a felony, it may be best to hire an attorney, he can decide if the prosecutorial venue is correct. If not, he can move for dismissal, but that does not mean the charges can not be refiled in the proper one.
