NY policeman Ramos funeral: 'A cop for the right reasons'
US Vice-President Joe Biden has paid tribute to a New York police officer shot dead a week ago.
Rafael Ramos and his partner Wenjian Liu were shot by a man who claimed to be avenging the killing of unarmed black people by police.
Mr Biden - who lost his first wife and daughter in an accident in 1972 - told mourners at Officer Ramos's funeral that he had been "a cop for all the right reasons".
