Strange that you can be so confident about this with private security when even actual police are sometimes involved in cases of excessive force, corruption, coverups. Besides, whatever your personal knowledge/experience is it can't be vast enough to prove a negative here, and only one counter example is needed.

Regardless of the year I think you might want to reconsider your overly confident notions about fiction/reality or at least the condescending tone. I don't know what is institutionalized in what places, but have been threatened by casino security. Fuck around and find out I guess

I'm kind of perplexed by the blanket assertions here as if private security everywhere will never offer either threatened or actual violence in either official or unofficial capacity.

Nevermind casinos, do people think every bouncer at every bar is merely for show? Since "management reserves the right", trespassing, threats and assault are not really a huge due-process kind of thing, and local establishments/insiders rank higher than outsiders. Within reason they know what is allowed and that isn't always going to be exactly and only whatever the law technically says.

Edit for even more context. For people that don't know already, not every casino or bar is owned by some megacorp who gives a shit about PR, has tons of cameras, has some HR department to educate staff on doctrine, etc. Many casinos are literally in sovereign territory of indigenous peoples also. Not that summary execution for offenders will be status quo there, but come on folks. The world is large and complicated, so simple stories about it are usually incomplete
