I don't think someone being a thief makes them cowardly, and thus not open to coming back and throwing a brick through your window in retaliation.

A thief is already open to the idea of invading your personal space for gain, why not revenge?

The man spent months and months developing this thing, is that not revenge?

I don't understand why everyone thinks the homeowners are helpless and just waiting to be robbed/vandalized/whatever.
