Trump: Actually, Stop-and-Frisk Only in 1 City He says Chicago is 'out of control' By Michael Harthorne, Newser Staff Posted Sep 22, 2016 2:51 PM CDT 176 comments Comments Donald Trump clarified his thoughts on stop-and-frisk policing Thursday.

(AP Photo/ Evan Vucci) (Newser) – After appearing to endorse its use nationally on Wednesday, Donald Trump clarified Thursday that he meant stop-and-frisk—a policing policy found to be inherently biased and unconstitutional in the past—should only be used in Chicago, Politico reports. "I was really referring to Chicago with stop-and-frisk," he said. "How it’s not being used in Chicago is, to be honest with you, it’s quite unbelievable." Trump said Chicago needs stop-and-frisk because it's "out of control" and being there is currently more dangerous than being in Afghanistan. According to USA Today, stop-and-frisk allows police to search people even when they aren't suspected of a crime. When asked for more details on his stop-and-frisk proposal, Trump explained: "If they see a person possibly with a gun or they think may have a gun, they will see the person and they'll look and they'll take the gun away." The practice was declared unconstitutional by a federal court in New York and studies have shown it to be biased. Chicago police were actually doing something similar to stop-and-frisk until they were threatened with a lawsuit by the ACLU last year, the Chicago Tribune reports. The ACLU found that Chicago cops were stopping a disproportionate number of black people, especially when they were in "white" neighborhoods.
