Lookin' at that teen 'stache of his, and how people have his address, why has nobody taken a swipe at his kneecaps with a baseball bat?
Now, sure, I understand that the Nell Carter-sized broad next to him is probably the muscle of the operation, but she can be distracted if you toss a ham sammich in the opposite direction of Steve.
Now, being quite serious, I think this cat needs his

ing ass beat, or therapy. Clearly all of his past incidents, well documented, easily traverse into "felony" territory (whoever estimed that he's ripped $300 of stuff couldn't be any further off). Now, if he's been approached before with his ways and made amends...it hasn't stopped him. With that in mind, nothing short of a felony charge with the threat of a prison sentence/fines/lifetime felony status could get under this guy's skin.
He needs to be brought down with a goddamned quickness, whether that's getting the police involved, or encouraging some Floridians to get whiskey drunk and send him to the hospital. Remember, this is NOT about *your* stuff. This is about everyone else who's been ripped off before, and those people he will potentially rip off in the future.
Vigilance!
