In my younger days I went the retaliation route on a few folks.

The older and wiser (and more valuable) I got, I decided it was much safer to take the high road. That way if things get really really nasty, my hands are clean and they can’t come after my assets. And win anyway.

I have used video cameras – home and auto – successfully to defend myself. Those things are worth every penny I paid for them. They’ve paid for themselves actually.
