Just how many of these so-called private security workers are armed?

Do they answer to the U.S. govt. or their employer if accused of a crime. I have a gut feeling that they are simply fired and shipped home. I am also concerned about their training and their experience. Is a criminal record's check mandatory?

All of these issues can be conveniently side-stepped when you send them to Iraq. Who is responsible for their conduct? I am not concerned about the unarmed who are there on legitimate business but the others...?
