There are a few policies that Sinyangwe said the evidence supports. There is not enough data, Sinyangwe said, to say that anti-bias training and classes are a solution. Instead, he points to strong restrictions on how police can use force, curbing the military-grade weapons distributed to the police and cracking down on police union contracts.
There is also an increasingly important conversation about defunding the police, which lawmakers such as Alexandra Ocasio-Cortez have resurfaced this week. The $6bn New York police department, for example, is bigger than the city’s budget for many housing, education and health initiatives.
“Part of police violence is policing of things that shouldn’t be policed,” Sinyangwe said, such as sending police to people having mental health crises. “To do that we have to make a divestment from policing and shift those resources.”
