Police from around US mourn with family of slain officer; thousands turn their backs on mayor

Police officers from around the U.S. joined grieving family members as they mourned a 32-year-old immigrant who realized his dream of being an NYPD officer but was gunned down in his squad car.

New York City Mayor Bill de Blasio and Police Commissioner William Bratton eulogized Officer Wenjian Liu (WEHN'-jihn loo) on Sunday as an incarnation of the American dream.

But thousands of officers turned their backs as de Blasio spoke, repeating a display of scorn for a mayor who many officers say is anti-police.

Liu had served as a police officer for seven years and was married just two months when he was killed with his partner, Officer Rafael Ramos, on Dec. 20.

The officers' killer committed suicide shortly after the brazen daytime ambush on a Brooklyn street.
