Hard to believe how many people are concerned by that. So a cowardly thief gets glitter bombed and you are worried that they will come back!! Imagine how much worse it would get for them.
Who wants to sign up for that?
A thief is already open to the idea of invading your personal space for gain, why not revenge?
I don't understand why everyone thinks the homeowners are helpless and just waiting to be robbed/vandalized/whatever.
