Look at the way this asshole is working that door knob.
I would electrify every piece of metal outside that is attached to the house. I would live in a taser essentially. Then ANY slithering prick who wanted to pull THIS kind of bullshit can get a surprise to go back and tell his buddies about...if he doesn't become crispy road kill of course. Personally I want to open my doors in the morning to see several of them smoking on my driveway. Some toddlers too if they ignore the warning signs.What? Supervise your stupid kids if they can't read. That just sounds like basic parenting to me.
