Will Contractors Lose Iraq Immunity? - TIME

Well, it appears that the US and Iraq are in the process of renegociating their security agreements, and the Iraqis consider the removal of immunity for contractors to be non-negotiable.

I think that this is the first time that the representatives of the Iraqi government are behaving in a way that is both beneficial to, and supported by its citizens regardless of ethnicity.

Good for them. As for the mercenaries, the rules in a foreign country are that if you do the crime, you do the time, in that country's jails.
