Imperfect self-defense?
Urinal targets? Sure.. I guess. But how about using it for real target practice. Wouldn't want to get too close, so make it life size and than let fly with something at least .308/30-06 class, and preferably .300 Win Mag or .50 BMG.
I'm afraid I'd not make a good cop. If I'd been the arresting officer, he'd look a lot worse than he appears in that photo, a whole worse.
