I'll say that an OPEN camera would cause a BUNCH of dudes to FLEE the place; as they STILL be inna closet!
No, hidden camera. Even the “outed” ones would leave otherwise. Those bars don’t get stings or even looked at. The laws don’t apply there, cops don’t go there unless called. I could go into the Dahlmer story again but you have probably read the account of the cops letting him take the naked, bleeding from the but and drugged boy back to his home....
