My neighbour and I caught 4 young punks trying to steal my Kawasaki some years ago. I had it chained to a post "for sale" around the corner from my house. Caught them by surprise and our intent was to scare them off ... you know run and yell at them. Well all 4 put their fists up and none wanted to run. ... too bad.
If you catch anyone trying to steal or break into your car, and they don't back down, then its game on!
I don't care what people think. Maybe y'all think I'm just a tough talker, keyboard warrior, whatever. I'm me, and I hate disrespectful people. I've grown up very much most of my life under discipline and respect, and if someone disses you or your property, you can do something about it ... but think about it before you act.
Peace
