“President Trump is again encouraging Chicago police to use stop-and-frisk – a policy that allows police officers to stop citizens without good cause – even as new government data reminds us why such policies can be disastrous for people of color. Just days after Trump endorsed stop-and-frisk in Chicago, the Bureau of Justice Statistics released its new report on interactions between police and the public, using survey data from 2015. The report reminds us that police stops and use of force are already racially discriminatory, with predictable consequences for public trust of the police.”
