Actually, in some places, the police wouldn't be at the donut shop - they would be 'taking a bite out of crime' giving seatbelt, speeding, no front license plate, etc., tickets. Revenue gathering, so to speak.
You usually will not be charged. In Dallas a few years ago, well maybe about 5 or so, a guy shot at some kids who where attempting to steal his car wheels, killed one of them. He even used a semi-auto firing a military catridge, an SKS, IIRC. The DA took the case to the grand jury, but the grand jury no-billed him, most likely because he was clearly acting within the law. Similiarly, more recently, maybe 2 years ago, a kid around 13 was shot and killed while stealing some chickens in San Antonio, same result although I can't recall if the DA even took it to the Grand Jury, I think not. These weren't ordinary eating or laying chickens, IOW somebody's livelyhood, but rather the guy's hobby. Both the deceased and his would be victim were hispanic. It was a sad case, the kid had a really horrid life, but that was and is irrellevant as far as the law is concerned.
