Something similiar happend here in Memphis a few years ago. The guy took coral from sale tanks and just dumped them, dry, into the pockets of a large coat. He did it a couple times before anyone realized what had happend. What tipped the LFS owner off was on one previous visit the guy jokingly asked one of the workers "How you think that would do in my pocket?"
I was persent for the next time he came into the store. LFS owner got an order banning the guy from the premisis and jail time if he called the cops and they caught him. Dude walked in (right after LFS told me the story and showed me the order) and got sent packing. Well, some time later a friend opened his own store and just to be safe got the same order out against the guy. Sure enough, I'm standing there talking to my buddy when this guy walks in. My friend orders him right back out and tells him if he ever sees him again he's going to jail.
Funny. Now that everyone in the community knows who he is, the guys practically shunned. When that LFS owner on that video says we're a "tight knit community" he isn't kidding.
