Yeah, like I said they do get away with it sometimes, but are usually fired if they do. If not criminally prosecuted. Most every company has big fear of being sued if a security guard seriously hurts someone and that fear is most often times baked very loudly into everything the guard sees or hears during onboarding.

Edit to add; no one is uploading videos of security guards doing nothing. Or at least those videos didn't get any traction.
