Does it matter? After the 30'th the Iraqis will not have any law enforcement or security forces, no Iraqi courts, the ones who will judge him are Americans.
For those of you who who STILL haven't got it (and think the puppet government means anything), Iraq will be in the hands of the US forces for another decade.
They may have no law enforcement, no security forces, every law they write has to be reviewed by the US, it is nothing more than a 51'st state inhabited by arabs, and the killings will continue... Until the US decides to remove the troops, then there will be a civil war, sometime around 2030 there might be peace and the US will claim they were successful once again.
