Dozens of people have rallied in Chicago outside a secretive police facility tied to the abuse and mistreatment of prisoners. The Guardian revealed last week Chicago police have used a nondescript warehouse known as Homan Square to conduct detentions and interrogations. Prisoners were allegedly denied access to their attorneys, beaten, and held for up to 24 hours without any official record of their detention. On Saturday, a group of demonstrators gathered at Homan to demand an investigation and the facility’s closure.

Protester 1: “When you became officers, you became public servants, not an extension of a military branch of the state. We are not the enemy.”

Protester 2: “Mr. Mayor, we demand an immediate, impartial investigation of Homan Square. We demand that you shut down this facility, at least so far as taking any accused people here. There are plenty of police lockups better monitored than this one around the city.”

Local activists have organized another rally today calling on Chicago to pay compensation to victims of longtime police abuse.
