Crossing state lines, with parts
And THAT is a huge part of the problem, 's far's I'm concerned. This so called probable cause can be invented easily on the spot. Since you are facing a combat soldier with at least some authority and multiple weapons, you are dead in the water. "If you have the money" you might be able to argue it out later in court. This does you no good at all at the time, on that lonely side of the road.
