If I was a club owner I would prefer an officer as well.
I just have concerns over the authority and repercussions. A bouncer has the right to walk you to the door. If you pull your arm away you don't get charged with resisting arrest. A bouncer may chest bump you and you bump him back - it's just a batter and the ump arguing over the plate. Same thing happens with an officer and you may end up with an assaulting an officer charge. I think knowing they have the same power of enforcement encourages a minority of them to act more aggressively. I think them wearing their uniforms alone lends a weight to their instructions.
