There are such swindlers in casinos.....CNBC's "American Greed" series ran the story about a Vietnamese group that swindled casinos out of millions.
They were very sophisticated, using electronics, and hordes of accomplices in the scheme, traveling from one casino to another ........was going great except for one huge boo-boo.
They hired people to participate---but one of them was an undercover agent who caught the ringleader on tape.
In one notorious casino swindling case-——the dealer was the swindler.
At first, casino security could not figure out how he was stealing.
They studied videotapes over and over-—then noticed the dealer was wearing a large watch——he would slip $100 chips under the face of the watch and walk out with them.
Accomplices would cash them in.
