Used to work contract security. my client was next to a MLB ball field- their parking lot literally was next to the service entrance, so the various staff that weren’t special (concessions, security, etc,) would park there. A lot of their ball game security are moonlighting cops or retired cops… they liked to tail gate after the game… but the city would revoke the license for running a parking lot if we allowed alcohol.
Getting drunken cops to leave your property when the other cops tried to be like “what’s the harm,” etc is no good.
