Great minds think a like.
Op, a few summers ago and group of teenagers for some reason spent the summer driving around in a car with a baseball bat, smashing mailboxes. I mean literally driving down the side of streets simply swinging.

my development has a block watch, contacted police, etc etc
One neighbor put in an inexpensive motion video camera. caught the guys and the car.
Rumor has it that not only did they get in trouble but evidently the charges were more serious because it was tampering with the US mail (who knew) and the owner of the car evidently was charged with a misdemeanor.
