American Torture Not New

(CBS/AP) Special prosecutors investigating allegations that police tortured nearly 150 black suspects in the 1970s and '80s said Wednesday they found evidence of abuse, but any crimes are now too old to prosecute.

In three of the cases, the prosecutors said the evidence was strong enough to have warranted indictments and convictions.

"It is our judgment that the evidence in those cases would be sufficient to establish guilt beyond a reasonable doubt," special prosecutors Robert D. Boyle and Edward J. Egan wrote.

The four-year investigation focused on allegations that 148 black men were tortured in Chicago police interrogation rooms in the 1970s and '80s. The men claimed detectives under the command of Lt. Jon Burge beat them, used electric shocks, played mock Russian roulette and started to smother at least one to elicit confessions.
