Mayor de Blasio should probably stop bragging about the fact that crime in his city has fallen to all-time lows.

In a series of shocking videos, NYPD officers can be seen being doused with buckets of water and pelted with projectiles as they tried to do their jobs (in one video, the officers were in the middle of making an arrest).

The stunning footage, which was first spotted online on Monday, shows the brazen young men in Harlem and Brooklyn dousing cops with water and, in one frame, an officer gets beaned in the back of the head with an empty red plastic bucket. The attacks on the officers started as they were arresting another young man, and in the video, they can be seen handcuffing the man while he was splayed out on the hood of a car.

Sources from within the NYPD and the officers union spoke with the New York Post about the "outrage" they felt toward both the criminals who carried out the attacks and the mayor, Bill de Blasio, who was out-of-state when the attacks occurred. Senior NYPD officials and union leaders have repeatedly criticized de Blasio for going easy on criminals and undoing some of the progress that happened under Mayors Bloomberg and Giuliani, where crime rates in the city began a dramatic slide (though, in recent years, crime rates have started ticking higher again).

"Everybody’s outraged," an NYPD source said. "It’s disgusting, embarrassing. There’s lawlessness around here now."

Police Chief Terence Monahan called the footage reprehensible and said every New Yorker must show respect for NYPD officers.

The videos of cops being doused with water and having objects hurled at them as they made an arrest in #Harlem is reprehensible. NYC’s cops & communities have made remarkable progress — together — but EVERY New Yorker MUST show respect for our cops. They deserve nothing less. pic.twitter.com/mPtPPbUSGZ — Chief Terence Monahan (@NYPDChiefofDept) July 22, 2019

Another officer blamed the incidents on the NYPD’s "hands-off approach to these guys" that Mayor de Blasio first advocated.

"Who does that in their right frame of mind? People who believe there’s no consequences," the anonymous officer said. "It's total anarchy. This is very sad."

Patrolmen's Benevolent Association head Pat Lynch, a longtime NYPD labor leader, called the water bucket attacks "the end result of the torrent of bad policies and anti-police rhetoric that has been streaming out of City Hall and Albany for years now."

The PBA Twitter account tweeted one of the clips, and insisted that we are approaching "the point of no return."

Lynch added that politicians don't care about the dangers of being an NYPD officer.

"As police officers, we need to draw a line. In situations like this, we need to take action to protect ourselves and the public. The politicians may not care about the dangerous levels of chaos in our neighborhoods, but police officers and decent New Yorkers should not be forced to suffer."

But de Blasio didn't mention the videos on his Twitter.

The two videos were initially posted on separate Instagram accounts, but they first picked up traction after being shared by a Twitter account devoted to NYC emergencies.
