Blackwater isn't just hiring people off the street.
I know that. If they want to continue to be involved in the military, they should stay in the military. Corporate profit and mercenaries should not be how wars are fought. How does a military function in a fully effective manner if it trains people then they move on to profiteering at the taxpayer expense, and not providing their expertise serving with those still in the military? Besides which, how can we trust them to not go to an even higher bidder (and potentially an enemy of the US) since they've already sold out to a higher bidder once?
