The Chicago Police Department is reported to have an unofficial black site, an off book location to "interrogate" suspects. Supposedly this has been going on for years. Information coming from a Chicago cop that tortured Gitmo detainees. Prisoners going to site are never booked and essentially disappear.

Rogue cops are one thing but this appears to be policy even if only talked about in whispers
