From [HERE] Last week, believing City Hall has betrayed them, mostly white cops demonstrated their anger Saturday by turning their backs on Mayor de Blasio as he entered a Brooklyn hospital to pay his respects to two murdered officers.

A startling video shows a hallway at Woodhull Hospital filled with officers silently facing away from de Blasio as he walks a blue gantlet. The demonstration, captured by WPIX11 News, included the presidents of the Patrolmen’s Benevolent Association and the Sergeants Benevolent Association.

“Mayor de Blasio, the blood of these two officers is clearly on your hands,” Ed Mullins [racist suspect in photo], president of the sergeants association, said in a statement to his union members Saturday night.

“It is your failed policies and actions that enabled this tragedy to occur,” he said. “I only hope and pray that more of these ambushes and executions do not happen again.”

Patrick Lynch, head of the PBA, echoed Mullins’ anger at the mayor.

“That blood on the hands starts on the steps of City Hall in the office of the mayor,” Lynch said in statement. “When these funerals are over, those responsible will be called on the carpet and held accountable.”

He added that the blame also goes to “those who incited violence on the street under the guise of protest that tried to tear down what NYC police officers did every day.”

“We tried to warn,” Lynch said. “It must not go on. It cannot be tolerated.”

Former Gov. George Pataki also lashed out against the mayor, claiming the cops’ deaths were a “predictable outcome of divisive anti-cop rhetoric of #ericholder & #mayordiblasio.”

Shortly after the officers were killed, a MoveOn.org petition was formed demanding de Blasio’s ouster.

“NYC residents demand the exit of Mayor Bill DeBlasio after 2 NYPD officers were shot and killed today 12/20/14,” wrote the petitioners, who identified themselves as “The People of NYC.” The petitioners said de Blasio was “unfit to lead this city” and “unfit to have a relationship with his police department.” [MORE]

But on Friday, current and former NYPD officers paid for a banner to fly along the Hudson River which says: "De Blasio, our backs have turned to you." [above]
