Yes. Because in casinos The counter always has to do business with you. (ie-they give chips, specifically to make everyone cash out.) You can review all the video of the winners. You can review the video of people around the winners. Etc etc etc. This makes card counters much easier to identify. A shoplifting ring operating in, say, a crowded walmart during the Christmas season may do business with you, or not? Just depends on their strategy. Maybe they just wait for the right number of black people to go into your store, and then clean you out and leave while security attention is elsewhere. Which one of the, statistically, 50% of 5 to 10 thousand people leaving the Walmart without purchasing that day was the shoplifter? That's a lot of film to go through. So in the case of casino security, the counters always have to present and identify themselves to you, making any review of a winner trivial. Whereas with retail security, that's not the case. This is a subtle but important distinction that, in the case of a large retail establishment, can significantly increase the difficulty of identifying shoplifters via film study. This is why in retail security, so much effort goes into identifying the shoplifter before they leave the store. Because if you can't make the attribution at that time, it's doubtful you ever will. In casino security, it's actually possible to identify the counters even after they leave the premises, and prevent their next visit.
