They are not "contractors"! They are MERCENARIES. Call them what they are. They are hired soldiers with no allegiance to anything but money and death.
They are also illegal. The United States should never be hiring mercenaries to fight our battles. The fact that they not only exist, but exist in larger numbers than our own legitimate troops, should scare the crap out of anyone who believes in a free country.
Blackwater = mercenaries.
Bush has built up his own private army. Can we impeach him for that?!???
