Mayor rips sgt. union as ‘racist’

No ’Shack attack

Mayor de Blasio labeled one of the city’s largest police unions as “racist” on Tuesday while discussing how the NYPD found “no criminality” behind the tainted milkshakes that sickened three cops.

“The SBA leadership has engaged in racist activities so many times, I can’t even count,” de Blasio said of the Sergeants Benevolent Association at a City Hall news conference Tuesday.

“I’ve been fighting with these unions from Day 1. These police-union leaders, not all of them, but too many of them, stand in the way of progress.”

The mayor claimed that leaders of the SBA and other unions have failed to help unite the city amid recent unrest and protests.

The comments came as it was revealed the drinks from Shake Shack that sickened NYPD cops in lower Manhattan Monday night were apparently tainted as a result of improper rinsing of a cleaning solution, not an attack.

“After a thorough investigation by the NYPD’s Manhattan South investigators, it has been determined that there was no criminality by [Shake Shack’s] employees,” Chief of Detectives Rodney Harrison tweeted.

The result of the probe led the Police Benevolent Association and the Detectives’ Endowment Association to retract statements suggesting that the cops were intentionally poisoned.

That’s when De Blasio praised Harrison “for so rapidly getting the truth out” and blasted the unions for jumping to conclusions.

“I would think the unions would trust the NYPD to find the truth,” de Blasio said.

“But the unions, these union leaders don’t want the truth, they just want to sow division, and we have to figure out what the limits are on their right to do that.”

First Amendment experts dismissed Hizzoner’s plan.

Lawyer George Freeman, executive director of the Media Law Resource Center, said de Blasio “is not constitutionally allowed to control the content of anyone’s speech unless it’s likely to lead to imminent unlawful action.”

“It was more bluster than anything else,” Freeman said.
