The porn was on, but there was nobody home. An NYPD officer inspecting a Bronx narcotics unit last week found a soft-core porn movie playing on one of the TVs in the facility, sources tell the Post. But there was nobody watching it, because all the officers had left for the day. Poor, lonely, neglected porn! The unidentified movie ("NYPD Blew"?), which was was playing on a satellite-TV premium channel, violates a departmental policy banning such channels at work. Well, at least it wasn't kiddie porn.
