When you hear a car alarm go off, do you think "omigawd, someone is trying to steal a car!" or do you think "shut that fuckin thing off!"?

IMO a killswitch deal would be a better idea..attatch it to the battery or EFI fuse and shut it off when you arent in the car. Just remember if they really want the car or something in it, theres almost nothing that can stop them!
