I was searching for the Tazer Club thingy my co-worker mentioned.
He saw it at a car security show a little while back and he thought it would be something worth investing in if you didn't want your car getting stolen.

Due to the high voltage it dispensed and literally put an adult to sleep, it was illegal in CA but legal in AZ where the car theft is like 4-5 times worse! And I am driving a full size truck which is at the top of a car thief's list!!

Then there is this more civilized and more expensive new gadget that supposedly beeps (at the receiver end which you can attach to your keychain) when the car alarm goes off. So when you are at the mall or sleeping or surfing pron and the thing goes off and you are within minutes of your car, haul @ss!! If I catch anyone messing with my ride, he is a dead man.
