Kihnu, we do not shoot guns in the air, you must be mistaking us for Iraqis and others from that part of the world.

These so-called "security contractors" are just an extension of the US military. Once the US troops have run their course of tormenting the Iraqi people while wearing the US military uniforms, they return to Iraq under the guise of "security contractors" and are right back at it again.
Poor Iraqi people will never experience freedom until all American military and armed security contractors are withdrawn from the country. With the exception, of course, of the few Marines needed to raise the flag at the monstrously massive US embassy in Baghdad and shoot their guns in the air on 4th of July. All the rest of the armed Americans must leave Iraq - or, eventually, they will be driven out by the Iraqi people.
