It's just his way of bringing momentary joy into freepers' lives, only to yank it away, à la Lucy and the football.
I would say its an admission of a guilty mind but he doesn’t feel guilty. He enjoys what he does. t is an admission that he knows exactly how completely his “perimeter patrol” is disliked and what some want for him.
What does he do for a living anyway with all that time on his hands? I keep considering dog poop scooper business or professional beer can smasher/recycler or something like that but if he’s earning a legit income I’m good with it, someone has to do those things (Ala Mike Roe). Maybe he’s retired so who knows.
