NY police shooting: Tributes paid at Rafael Ramos's funeral
Thousands of police officers have joined family, friends and dignitaries at the funeral of Rafael Ramos, one of two New York policemen shot dead a week ago.
Officers Ramos and Wenjian Liu were shot in their patrol car after weeks of anti-police protests.
Some of the officers at the funeral turned their backs on New York Mayor Bill de Blasio, who they feel has encouraged a climate of mistrust towards the police.
