Papers now! You must prove your innocence to me on the side of the road!
BGOS, much? You are innocent until proven guilty in a court of law. You don't have to show documentation of any kind to anybody but your lawyer. The state must prove you are guilty of committing a crime, not you proving your innocence.
Believe me, until you start playing the NFA game you don't know what it's like having to carry documentation. But then again you are only required to show the NFA documentation to a ATF agent. Nobody else can demand to see it.
Could be the BGOS in me, Maryland is good for that...of course the military checkpoints in our nation’s capital don’t bolster my faith either in due process under our rights. For the record I have only been pulled over once in the last 15 years and I got a warning and wasn’t even asked about weapons or anything in a fishing expedition.
