NYPD officers gave a salute to embattled mayor Bill de Blasio as he mounted the steps of the funeral home where the wake is being held for slain officer Wenjian Liu. The gesture of respect follows weeks of sniping at the mayor from rank-and-file members, culminating in many of them turning their backs to him at the funeral service for Officer Liu's partner, Rafael Ramos. Somber NYPD officers flocked to the wake for the slain officer - the second of two men murdered as they patrolled the streets together last month. Uniformed cops thronged the streets around the Aievoli Funeral Home in Brooklyn, New York to pay their respects to Liu, 32, who will have a full funeral Sunday.
