The Pentagon contractor CACI has lost a bid to dismiss a torture lawsuit brought by four former Abu Ghraib prisoners. On Thursday, a federal judge made public a ruling rejecting CACI’s claim to be immune from prosecution. The case also names the company L-3 Services, as well three individual contractors. One of the plaintiffs, an Iraqi farmer, alleges he was caged, beaten, threatened with dogs and given electric shocks during more than four years in US detention.
