John Jay cop-hater badgers de Blasio

A John Jay College of Criminal Justice professor in the hot seat for a despicable anti-cop tweet blasted Mayor de Blasio on Saturday as being the one who’s really “anti-police.”

“He messed up big,” antifa activist Michael Isaacson wrote of the mayor at 8:23 a.m., retweeting Hizzoner’s critical comments from the day before, in which he said the city “won’t stand for the vile anti-police rhetoric.”

“First @NYCMayor has taken a swipe at the administrative autonomy of John Jay College and CUNY,” Isaacson complained. “Second, @nycmayor has taken a swipe at free speech and academic freedom. Third, @NYCMayor is placating PBA with a costless symbolic demand to avoid having to meet the MATERIAL demands in contract negotiations.”

Isaacson (right) went on: “Keep in mind this is the same @NYCMayor who was protested by that same PBA for balking on a 1% pay increase. Who’s really anti-police here?”

Isaacson, 29, sparked controversy Friday when an Aug. 23 tweet of his came to light: “Some of ya’ll might think it sucks being an anti-fascist teaching at John Jay College but I think it’s a privilege to teach future dead cops,” Isaacson wrote. The tweet prompted criticism from police unions and city officials, including de Blasio. Isaacson has since been suspended. City Hall spokesman Austin Finan scoffed at Isaacson’s Saturday screed.

“Comments as ignorant as these don’t deserve a response,” he said.

On Saturday, Patrolmen’s Benevolent Association boss Pat Lynch said Isaacson needs to be “fired immediately.”

John Jay President Karol Mason has called Isaacson’s views “abhorrent.”
