WASHINGTON — Michael Bloomberg is under fire for resurfaced comments in which the Democratic presidential candidate says the way to bring down murder rates is to “put a lot of cops” in minority neighborhoods because that’s where “all the crime is.”

The billionaire and former New York City mayor made the comments at a 2015 appearance at the Aspen Institute, as part of an overall defense of his support for the controversial “stop and frisk” policing tactic that has been found to disproportionately affect minorities.

Bloomberg launched his presidential bid late last year with an apology for his support for the policy. He’s taking an unconventional approach to the campaign, bypassing the traditional early states and gaining attention by flooding the airwaves with hundreds of millions of dollars in ads. He’s spent recent days courting black voters whose support will be crucial to winning the Democratic nomination and will begin a campaign swing through the South on Wednesday.

Seeking to blunt any political fallout from the comments, Bloomberg said Tuesday the remarks “do not reflect my commitment to criminal justice reform and racial equity.”

But the audio of his Aspen speech highlights his embrace of the policy just a few years ago and suggests he was aware of the disproportionate impact of stop and frisk on minorities. Bloomberg says that “95%” of murders and murder victims are young male minorities and that “you can just take the description, Xerox it and pass it out to all the cops.” To combat crime, he says, “put a lot of cops where the crime is, which means in minority neighborhoods.”

In the audio, he acknowledges that focusing police forces in minority neighborhoods means minorities are disproportionately arrested for marijuana possession but dismisses that as a necessary consequence. “Why do we do it? Because that’s where all the crime is,” Bloomberg said.

And to “get the guns out of the kids’ hands,” Bloomberg says, police must “throw `em against the wall and frisk ‘em.”

“And they say, ‘Oh, I don’t want that. I don’t wanna get caught.’ So they don’t bring the gun,” he says.

According to a report in the Aspen Times that year, Bloomberg blocked the release of video of the Aspen Institute appearance. But the Aspen Times reporter uploaded what appears to be the full audio online, and it drew renewed attention Monday after podcaster Benjamin Dixon circulated it on Twitter.

In his Tuesday statement, Bloomberg notes that he “inherited the practice of stop and frisk” from Rudy Giuliani’s administration and noted that by the time he left office at the end of 2013, he had significantly reduced its use. He said, “I should have done it faster and sooner.”

But stop and frisk expanded dramatically on Bloomberg’s watch, reaching a peak in 2011 when over 685,000 people were stopped, according to data from the American Civil Liberties Union. While its use declined significantly after that, Bloomberg stood by the program even in the face of widespread criticism and legal challenges.
