This as New York City's police commissioner said the gunman who ambushed and killed two police officers had made online posts that were 'very anti-police.'

Police Commissioner William Bratton choked up at a news conference at the Woodhull medical Center on Saturday afternoon as he talked about the fatal shootings of two officers in Brooklyn's Bedford-Stuyvesant neighborhood. Meanwhile, an eyewitness who spoke toThe Daily Beast said that 'a lot of people were clapping and laughing' following the murder of the two police officers.

'Some were saying, "They deserved it," and another was shouting at the cops, "Serves them right because you mistreat people!"'said the man, identified as Carlos.

'They were, quite simply, assassinated — targeted for their uniform. … They were ambushed and murdered,' said Bratton.
