Leaders in New York City are blaming an ambush on police officers there on an atmosphere of anti-police rhetoric.
Authorities say a gunman was taken into custody Sunday after attacks that morning and the night before wounded two officers.
Police Commissioner Dermot Shea lashed out at activists who have held demonstrations against excessive force by police in recent months. Shea didn't offer any evidence that the gunman knew of those protests or was influenced by them.
A leader of police reform activists says it was irresponsible for Shea and Mayor Bill de Blasio to link the violence to the recent demonstrations.
