"Look what happened to your car."

I am not a violent person. Nor am I likely to engage in vandalism. But I  will admit that I would have no problem with anyone taking a sledgehammer to a car—no matter how expensive—whose alarm continues to go off without anyone showing up to stop it. I frankly feel nobody has the right to disturb the general peace to protect their property unless they are prepared to be nearby and address the robbery. Right now I working on my computer and every five minutes I have to listen to loud minutes-long whining of a loud car siren. Ah, the wonderful fantasies I have of spray-painting that car or tossing a huge brick through its windshield. Would I actually do anything that outrageously illegal if I thought I could get away with it? You bet.
