Switzerland. The Republic and Canton of Neuchâtel. Neuchâtel. Downtown. Narcotics squad. "Narko" operation. Three police officers on duty (both in plain-clothes) arrest a drug dealer from Western Africa and his customer. The convict black man is handcuffed because he was caught selling illegal drugs (cocaine) in the streets. Plainclothes law enforcement is a method used by police. The policemen wear plainclothes or "ordinary clothes" instead of a uniform in order to avoid detection or identification as law enforcement agents. Police officers in plainclothes must identify themselves when using their police powers. 1.04.15 © 2015 Didier Ruef
