U.S. Attorney General Eric Holder has announced the Justice Department will launch full criminal investigations into the deaths of two prisoners killed in CIA custody, including one who died at the Abu Ghraib prison in Iraq. But Holder said no criminal probes will occur in 99 other cases of alleged torture, abuse and murder reviewed by federal prosecutors. The criminal probes were announced on Leon Panetta’s last full day as CIA director. Panetta will be sworn in as a Defense Secretary today. The Senate on Thursday confirmed Gen. David Petraeus to become the new CIA director.
