New York City Mayor Bill de Blasio called slain NYPD officer Wenjian Liu a courageous family man who followed "a path of kindness" as he addressed a crowded funeral home in Brooklyn Sunday.
While many officers listened respectfully, some still turned their backs in protest, as they had done previously, at Liu's partner's funeral a week ago.
Earlier in the day, thousands of NYPD officers and mourners crowded a funeral home, joined by law enforcement official from throughout the country.
Buddhist monks led a Chinese ceremony for the 32-year-old officer, followed by a police ceremony and eulogies led by a chaplain. Officers lined up for blocks outside the Aievoli Funeral Home in the Bensonhurst section of Brooklyn to pay their respects.
