Cameras wouldnt do much - the store would just have a video of it happening, and nobody would know who the punk was anyway.
I'd sure like to catch some ******* doing that. My truck or not, he'd get messed up.
I actually had the good fortune of catching one of them in the act...
I was in college and had a Mazda MX-6 with a nice stereo in it, parked it right outside my bedroom window. One night I get woke up by a window breaking, and I think "please don't let my car alarm go off..."
Next thing I know it does, it only would go off when someone unlocked the doors from the inside (stupid I know, but it was a factory alarm). So I spring out of bed in only my underwear and haul ass for the door.
I get outside and see the little ******** leaning into my car to pull the stereo and yell something to the effect of "Hey ************!" and he sees me, drops his hammer and starts to run.
Thinking quickly I run after him and grab the hammer on my way by. So I'm chasing him barefoot in my underwear, screaming at him about how I'm going to bash his ******* skull in with the hammer if I catch him. I chased him probably a block before I gave up and realized I was in my underwear along a main city street. Bummed I didn't catch him, but I'm pretty sure he thought he was gonna die that night.
He didn't get my stereo and I still have that hammer too...
