Switzerland. The Republic and Canton of Neuchâtel. Neuchâtel. Police station headquarters. Narcotics squad. "Narko" operation. A group of police officers in plainclothes listens to the daily briefing. A policeman listens with earphones to various telephone tappings regarding drug dealers' police investigations. 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. A police station or station house is a building which serves for police officers. The building contains temporary holding cells and interview/interrogation rooms. Telephone tapping (also wire tapping or wiretapping in American English) is the monitoring of telephone and Internet conversations by a third party, often by covert means. The wire tap received its name because, historically, the monitoring connection was an actual electrical tap on the telephone line. Legal wiretapping by a government agency is also called lawful interception. 1.04.15 © 2015 Didier Ruef
