"The examples given by The Guardian, with regard to the shackling, with regard to the sensory deprivation, with regard to the beatings, the kicking in the groin, and the food deprivation, amount to torture or cruel and unusual and degrading treatment under CAT," Taylor said on Friday.
In February, the Guardian reported that the CPD operated a "domestic black site," similar to US Central Intelligence Agency (CIA) interrogation sites overseas, in Homan Square on the city's Westside.
Taylor said the case should be escalated to the UN if local and federal officials fail to conduct an adequate investigation into the reported abuses at Homan Square.
"If there is not a sufficient investigation here [Chicago], or by the [US] Justice Department, then people should consider taking it to the United Nations," Taylor added.
"In the mid-2000s we did take it internationally, both to the Organization of American States, their human rights commission, and to the CAT itself in Geneva. My partner Joey Mogul presented it to the CAT," Taylor explained.
"And they [the UN] came out with a statement that called for prosecutions of Burge and others for the torture here in Chicago and put it on the same plane with Abu Ghraib and Guantanamo. So that was an international vindication of our position that it was systemic torture under Burge," Taylor added.
More than 100 Chicago residents of color were tortured between 1972 and 1991, according to Amnesty International USA. Jon Burge, the then-Chicago police chief, was convicted in a federal court for perjury and obstruction of justice, but was never prosecuted for torture. Burge was released after serving fewer than four years in prison.
