There has been a running battle over the last several weeks between New York Mayor Bill de Blasio and police unions over the nauseating manner in which hizzonner has pandered to the people protesting the grand jury decision not to indict officers in the killing of Eric Garner.

De Blasio has expressed sympathy for the protestors and the cops think he has thrown them under the bus. Today, de Blasio's chickens came home to roost as the execution style murder of two New York city cops has the police force so angry, that when the mayor entered the hospital to pay his respects to the dead officers, the Thin Blue Line reacted by turning their backs on him en masse.

New York Daily News:

Believing City Hall has betrayed them, cops demonstrated their anger Saturday by turning their backs on Mayor de Blasio as he entered a Brooklyn hospital to pay respects to two murdered officers.

A startling video shows a hallway at Woodhull Hospital filled with cops silently facing away from de Blasio as he walks a blue gauntlet.

The demonstration, captured by WPIX11 News, included the presidents of the Patrolmen’s Benevolent Association and the the Sergeants Benevolent Association.

“Mayor de Blasio, the blood of these two officers is clearly on your hands,” Ed Mullins, 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,” Mullins said. “I only hope and pray that more of these ambushes and executions do not happen again.”

Patrick Lynch, head of the patrol officers’ union, 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.”

De Blasio has been playing with fire for weeks, but it's not just the protests that has the cops up in arms. Many officers believe that de Blasio's policies have made their jobs more difficult - and dangerous:

“Ever since this mayor took office there has been a sense of lawlessness that is rampant in every borough,” Mullins said in his statement Saturday night.

He noted that even Police Commissioner Bill Bratton was attacked in Times Square by protesters who splattered him with red paint at a Nov. 25 demonstration.

“If we can’t keep the PC from danger, what lies ahead for all of us?” Mullins said.

Indeed. De Blasio thought he could have it both ways, but the cops saw through that immediately. Their actions at the hospital yesterday speak lounder than any statement put out by their union leaders.
