Three Iraqis and a Jordanian filed federal lawsuits Monday alleging they were tortured by U.S. defense contractors while detained at the Abu Ghraib prison in Iraq in 2003 and 2004. The lawsuits allege that those arrested and taken to the prison were subjected to forced nudity, electrical shocks, mock executions and other inhumane treatment. They seek unspecified payments high enough to compensate the detainees for their injuries, and to deter contractors from such conduct in the future... The contractors named as defendants in the lawsuit are CACI International Inc....and...L-3 Communications Corp., formerly Titan Corp... The lawsuits repeat "baseless allegations" made more than four years ago in another case brought by the same lawyers, CACI spokeswoman Jody Brown said in a statement.
