A New York police union leader has blamed nationwide protests for the deaths of two New York police officers.
The officers were killed without warning as they sat in their patrol car in Brooklyn by a gunman who then killed himself.
Thousands of people have rallied across the US to protest police killings and the decisions not to indict the white officer involved in the chokehold death of Eric Garner, and the officer who killed unarmed black teenager Michael Brown.
