Ain't that the truth! My truck was broken into back in '06 the same way schmule's was - screw driver under the lock. They stole my stereo head unit (which I took the face off of and took with me, odd) and tried to start my truck as my ignition switch and transmission lever were all jacked up. This was in the middle of the day in the middle of a busy parking lot. It amazes me how people don't notice the things that go on around them. If someone did see who did it, did they really just think the guy was doing a quick stereo install the parking lot of a sporting goods store? lol Or, like you said, why can't people just leave stuff alone that's not theirs? Ever since then, I have wondered about anti-theft devices, like a piece of metal behind the lock to keep things from being stuck in there. I suppose a loud alarm is about all you can do. Like Kady said, there is no solid way to keep people out if they really want in, but if you had a loud enough alarm, hopefully the noise attracting a lot of attention will make the perp run off. My best efforts include trying not be a target. Tinted windows, not keeping valuables in the car, hiding things that are in the car, etc.
