hey popular hotrodding or one of those mags did a test in New York on those alarm horns they put a car on a street, and set it off to see what would happen after 10min some one broke into the car,a nd stole the stereo, 5min later someone came, and stole the tires, some one else broke all the windows, and keyed the side after about 45 min the cops showed up, and wrote a ticket for disturbing the piece, and left it on what was left fo the window.
