"The Guardian has uncovered arrest records revealing that 82% of the more than 3,500 Americans detained at a secret police facility in Chicago over the past decade were black.
About 8.5% of those held at the site were white. According to the 2010 census, Chicago's population is 32% non-Hispanic white, 33% black, and 29% Hispanic (of which 13.5% identify as racially white) .
In February, The Guardian reported that the Chicago Police Department was holding US citizens for days on end at the facility known as Homan Square. Suspects had no contact with the outside world and were treated and interrogated like terrorists at so-called US black sites."
