I spent a year in PRNJ, and found out that you can't even buy a pellet rifle without a ton of paperwork and approval from the rulers.
I wouldn't try to carry a weapon there, and I wouldn't be on a trail there unarmed.
At trial Brian Aitkens defense team showed the jury Brians three FBI background checks to lawfully purchase firearms, a number of witnessesincluding a Mount Laurel police officertestified that Brian was moving between residences and all witnessesincluding the Mount Laurel police officertestified that Brians firearms were unloaded & locked in the trunk of his car exactly as New Jersey State Law requires
Brian knew how to do this because he had called the New Jersey State Police days earlier to ensure he was in compliance with the law
a fact the Judge ruled inadmissible in the court room.
