I think they're only casino cops, but they're just as lazy as real cops. When the fight breaks out, they do what any normal citizen would do. Stand around and watch. I guess as long as the guys aren't fighting in the casino, they don't give a shit. You would think they'd at least take the opportunity to taser someone or give a beating with their club. But that would take effort, which clearly these wannabe pigs aren't willing to put forth.
