New York City’s Democratic Mayor Bill de Blasio said Tuesday that Donald Trump’s Monday debate claim stop and frisk was the reason for the murder rate’s decline from 2,200 to 500 homicides was “literally all wrong.”

“Crime comes down because Mayor Dinkins has a lot of police and Bill Bratton puts on a much more strategic system for police. Crime goes down. It was not used during the Bloomberg years, the unconstitutional overuse of stop and frisk. Indiscriminate stopping primarily of young men of color,” de Blasio told MSNBC host Christopher Hayes on Tuesday evening.
