Soldiers are usually protected from charges of people getting killed and still are in collateral loss, that appears to be what happen here and Mercs hired by the govt have always been protected in the same way.

As to them lining their pockets, they were hired to do a job and paid wages for doing that job, there is no "Lining of pockets" off the misery of the Iraqi, they are doing the job they were hired to do.
The hiring of mercs for security work has been done for many years in case that you didn't know it, but a lot of uninformed people think it is something new, it isn't.
The troopers that were tried in the murder/rape trial is something new and usually does not happen, very rare circumstance.
Now if you want to cry about the poor unfortunate Iraqi, Or muslims in general, why not switch to how many thousand have been killed by their own people in bombings and plain outright murder/beheadings.

And they might have canceled the permit to work for Blackwater, but that does not prove that it did anything wrong, so where is the proof that they did in fact fuckup? there is no big deal about a contract or permit being canceled.
You just RANT with no proof of wrong doing, are you jealous because you have to teach for 15k baht a month when that is less than a mercs pay for one day?
