An off-duty NYPD officer was arrested Sunday night after waving his gun at a group of rowdy, belligerent Rangers fans. For some reason, that's a crime, and Officer David Hendrick, a 16-year veteran assigned to the Manhattan Task Force, faces a felony charge of criminal possession of a weapon and a lesser charge of menacing. MTA cops stopped the Ronkonkoma-bound train in Mineola after several frightened passengers called 911 to report that a man had brandished a gun.
