I don't live in Las Vegas, but I agree with Tyrus that it's 100% Hollywood. I was amused by one episode a couple of weeks back. They were reviewing surveillance videotape that had been previously shot in a nightclub in the casino. Keep in mind, this is TAPE, not live. They were able to zoom in on a guy across the room and not only see him drop a tablet into somebody's drink, but they could READ THE WRITING ON THE TABLET! I know technology has come a long way, but I think that was a little much.
