so your employer has a right to search you car for guns?
when i park at school (no guns in my truck, but lots of tools, wrenches and a pocket knife) i work on a farm, and at a machine shop, if they want to take away my knife, we can fight over it, and i will win. no person is going to deprive me of mankinds oldest tool. (besides if the blade isnt over 3'' its legal anyways...)
i lock the door, roll up windows, the school needs my permission to search unless they have evidence of drugs, (like a bag of pot on the dash, or the drug-dog starts barking) if they search without my permission, they will have to pick the lock, and thats going to court.
if they ask me if they can search, i say no. if they throw a bunch of bullsh** saying its their property and they have a right to search, i give them my phone and tell them to talk to dad and our lawer. nuff said
