Previously, the union had sought to have the mayor banned from the funerals of police killed in the line of duty.
The union said the request was made because of de Blasio's "consistent refusal to show police officers the support and respect they deserve."
But there hasn't been a mayor, Republican, Democrat or Independent, in at least the recent past who hasn't been met with scorn by the powerful police union.
As former New York Times reporter David Firestone pointed out in a series of tweets:
At least the last four administrations, spanning nearly 25 years, have faced heavy criticism from the PBA.
For his part, de Blasio has asked that all protests against the killing of unarmed African-American men by police officers be suspended until after the funerals of the slain NYPD officers.
"It’s a time to step back and just focus on these families," he said. "I think it’s a time for everyone to put aside political debates, put aside protests, put aside all of the things that we will talk about in due time. In the coming days, as two families prepare for funerals and figure out how to piece their lives back together, that should be our only concern: How do we support them?"
De Blasio's police commissioner, Bill Braton said the mayor had lost the trust of "some" of his officers. Braton's comments came after NYPD officers turned their back on the mayor following a visit to Woodhull Hospital, where the two fallen cops were pronounced dead Saturday.
"I think he has lost it with some officers," Bratton said. "I was at the hospital when that event occurred.... I don't support that particular activity, I don't think it was appropriate, particularly in that setting, but it's reflective of the anger of some of them."
De Blasio angered the police union after he admitted that he had to train his bi-racial son to be extra careful during interactions with police.
"What parents have done for decades who have children of color, especially young men of color, is train them to be very careful when they have a connection with a police officer," de Blasio said. "It's different for a white child. That's just the reality in this country."
Previous research has shown that black men are 21 times more likely to be killed by police than their white counterparts.
