While stop-and-frisk plagued New York’s minority communities, in Chicago, police similarly made street stops that a study by the American Civil Liberties Union found targeted blacks and Latinos in lower-income communities. The 2015 study found that Chicago police made more than 250,000 stops that did not lead to an arrest in mid-2014 — which was much higher than similar stops in New York. The Chicago study and a subsequent lawsuit led to reform measures that are still being worked through.
