Former NYPD Commissioner Ray Kelly once boasted that his department-- which he described as a "quasi-military organization"-- had “some means to take down a plane" if necessary.

It was this same militarized police force that, under Kelly, conducted a midnight raid on Zuccotti Park in lower Manhattan in 2011, rounding up and arresting journalists and scores of Occupy Wall Street protesters.

It was Kelly who defended his department after the Associated Press uncovered its surveillance of the city's Muslim communities.

Amidst growing outrage, Kelly also defended his department's use of stop-and-frisk. Hundreds of thousands of New Yorkers were stopped by police during his stint as commissioner, the overwhelming majority of whom were black or Latino.

And it was during Kelly's tenure as commissioner that police officers killed Sean Bell, Tamon Robinson, and Ramarley Graham -- all unarmed black men.

And yet, even Ray Kelly thinks police in Ferguson, Missouri, have gone way too far in their handling of the turmoil after the death of 18-year-old Michael Brown, who was shot and killed by police officer Darren Wilson last week.

"The toothpaste is out of the tube here," Kelly told Bloomberg News. "There's lots of things that should have been done differently, and you have to live with them."

The department's first major misstep, Kelly said, was not immediately releasing all of the information surrounding Brown's death. Telling the public what happened “certainly has the potential for quelling or lessening disturbances,” Kelly said. “You tell them what you know and tell them what you don’t know, rather than dribbling it out.”

Kelly also said it was "mind-boggling" that the Ferguson Police Department has 50 white police officers and just three black police officers in a town that's nearly 70 percent black.

Attorney General Eric Holder will travel to Ferguson on Wednesday to meet with investigators looking into the teen's death. A grand jury inquiry into Brown's shooting could also begin gathering evidence on Wednesday.
