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 Aitken’s defense team showed the jury Brian’s three FBI background checks to lawfully purchase firearms, a number of witnesses—including a Mount Laurel police officer—testified that Brian was moving between residences and all witnesses—including the Mount Laurel police officer—testified that Brian’s 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.
