Via NY Post:

After just 15 minutes inside, Hizzoner left alone, again out of sight of the throng of officers still waiting to enter the wake.

“It just shows that de Blasio is worried and he’s stacking the deck to protect himself and his image,” one law-enforcement source said of the mayor’s media-savvy decision to enter the wake quickly, quietly, away from the blue wall of resentment, and with “bodyguard” Bratton in tow.
“Bratton will do anything to help him,” the source added.

and police were planning for today:

In the weeks since Liu and partner Rafael Ramos, 40, were ambushed Dec. 20 on a Bedford-Stuyvesant street, angry officers have displayed outrage to their perceived, anti-cop mayor by literally turning their backs on him as he passed them in a hospital hallway and as he spoke at Ramos’ funeral last Saturday.

And while no officers turned their backs on the mayor at Liu’s wake Saturday, cops were plotting online to do so at the slain officer’s funeral Sunday, despite an NYPD-wide directive by Bratton that “a hero’s funeral is about grieving, not grievance.”

“There will be someone signaling an ‘ABOUT FACE’ via bullhorn,” one poster who used the handle “BrutalObserver” wrote on Thee Rant blog. “If and when you hear this loud ABOUT FACE everyone… and I mean everyone is expected to face away from the funeral home.”

“Sympathetic friends in IAB [Internal Affairs Bureau] and Brooklyn inspections have already confirmed that they will be sending an ample contingency of rat observers to the funeral armed with pen and pads,” the poster warned.

Officers who are “on the fence” about protesting can wear their raid jackets over their uniforms, the poster suggested. “This way you are identified in the press but the rats in the crowd can not write down your shield number.”

Bratton has said he won’t punish officers who again disrespect de Blasio, but has said such behavior is “inappropriate.”
