The electrical engineer types in the office suggested that they put plastic bushings on the flap and electrically insulate it from the surrounding frame - and they did. Connecting a car battery to the flap and frame, they set up their surprise. Sure enough, the next morning there were chunks of burned skin stuck to the mail slot. Problem solved.

I’m certain the guy doing that was down on his luck, but there is a certain level of dignity you maintain. If you can’t maintain it, then you’re seeking trouble and you’ll find it.
Doing what this guy was doing goes beyond common decency, so you know, he got just what he deserved.
If the guy sought medical care, he would have been seen by professionals that would ask where he got incurred the injury.
Hearing the story, they could notify the authorities.
I’m glad this didn’t come back to haunt the business owner.
