I'm not killing anyone for screwing with my car, and I hope most folks feel the same way. Yes, it sucks. Yes, I'd be more than pissed. But I'm not going to murder another human for a property crime.
Self defense and defense of property is not murder. So many street trash shit on regular families just trying to get by precisely because of sympathy for dirtbags who shouldn't be drawing the same breath as normal people.
