Porecting the outside using electircity is a problem. Iw as going to to this myself. hehe...love the legal. Anyways, theres gotta be a way to proect the inside. Honestly...i was going to be a bit more insidius. Maybe a contact neurotoxin that paralyzed the person's extermiity for a few minutes. I mean really...who continues to steal a car when they can't feel anything above thier elbow? Itching powerder and skin irritants, things that won' kill, they can't really prove without saying that "i tried to break into the car", things that would stop them in their tracks and make them reconsider. I mena, my firned has an immobilizer that works AFTER the car is started. If the car stops and kills the guy ro critically wounds him, r another person, apparently, the theif is liable.
hmmm...how about a nice dose of knockout gas or nitrus oxide? Show me a state that bans laughing gas, i'll show you a state full of bad teeth
