Sgt. Javal Davis, who admitted abusing detainees at Abu Ghraib in late 2003, was sentenced Friday to six months in a military prison and given a bad-conduct discharge from the Army. A nine-man military jury deliberated for about 5 1/2 hours before sentencing Davis, a former Abu Ghraib guard who earlier this week confessed to stepping on the hands and feet of a group of handcuffed detainees and falling with his full weight on top of them.
