Yale professor Dr. Phillip Atiba Goff co-founded the Center for Policing Equity, which collects data on police behavior from 18,000 law enforcement agencies across the country. He says most people think of racism as an issue of character and ignorance. But, he says, focusing on changing racist attitudes is "a bad way to stop the behavior," He says. "The best way to regulate behavior is to regulate behavior. And that's what we can do in policing. That's what we can do in our communities. That's what we can do with policies."
