Weird to describe these guys as good Samaritans considering how relentlessly they smashed this guy to pieces but I guess adrenalin is going to take over any time you see some dude jump into a car with a mum and her young child inside and try to steal it.

The thief puts in a decent effort trying to escape but these San Diego peeps are all over him, with one guy stomping the shit out of his fingers in one particularly brutal move.

The man was eventually arrested and taken into police custody:
