You are a gun dealer. You start selling Montana guns to Montana residents. BATF takes your license and shuts your store down and puts charges against you for illegal gun transfers. You find yourself in FEDERAL DISTRICT COURT. You are convicted and wind up in Leavenworth (which for some reason is where most people with Federal gun charges go). ALL of your appeals take 5-10 years. Your win but your life is ruined.
Which BTW I do not believe you will win. Federal prison for 7-10 years.
