I doubt that any casino will answer this question, but with the discussion about the trend toward removing live gaming tables and replacing them with electronic table games, couldn’t the casinos reduce the number of security officers? I realize they would have to have some, but I was under the impression that the majority of them were primarily there to watch over the games.
To a certain extent, you're confusing security with surveillance. Surveillance is the primary protectors of the games; they call security when a player (or a dealer) is being escorted off the property for one reason or another. Security also shows up in the pit if there's a fight, or extreme drunkenness, or a guest is having a medical episode, money and chips are being transferred in and out, etc.
Now, it's true that with more and more live pits shrinking in favor of ETGs, surveillance agents could be reduced. Artificial intelligence is automating player tracking, streamlining database management (such as picking off trespassed patrons), making cameras more effective, controlling chips through RFID tech to where whatever live personnel are left are being incorporated into the surveillance system. If anything, that might mean more security officers as AI identifies APs, shot-takers, cheaters, and the like.
But the bottom line, as we see it, is that wherever masses of people gather to play games, with a lot of money, free alcohol, loosened inhibitions, and bad behavior in the mix, the need for security will be as prevalent as ever.
