Why Cant We Send Prisoners To Iraq?

Some time ago, I discussed this with a friend who is an assistant warden. He had so many reasons!They can't be trusted to do as they're told.They can't be trusted with weapons. They could easily be bought off by the enemy. They would not be appropriate representatives of our country. More than anything, they have been sentenced to serve a certain sentence, and until that's completed, they can't be let out of prison facilities without jeopardizing the entire justice system. If a sentence is something like life or war, most would take war, and many of them would take off as soon as they left the prison. What other deals would that lead to? I don't agree with all of that, and there were many more reasons in the conversation, but I wouldn't think it appropriate to put convicted criminals ouo the world to represent the US.
