Can an off-duty police officer working private security stop traffic to allow cust. to turn into business?

Question

To further clarify... Off duty Police Officers (Police uniformed), working private security for a medical clinic's parking deck entrance (non-emergency) are stopping legally flowing traffic to allow the clinics customers to make illegal turns into the parking deck?

Answer 1

If they're allowed to wear their uniforms (under what I have to assume is an agreement with the local office) then they are acting with the authority of an on-duty policeman and can legally perform traffic direction in order to alleviate congestion or safety concerns.  

Answer 2

Yes he can do this. Really, who cares? Are you looking for something to complain about? If it's causing a traffic hazard, report it to the police department and they will handle it internally. (Tell him to stop.)

Answer 3

a police officer can not use his or her powers to break the law, like allow people to make illegal U turns.
