First, the title of this was intended to be a double entrendre —
"They keep talking about drafting a Constitution for Iraq. Why don't we just give them ours? It was written by a lot of really smart guys, it's worked for over 200 years and, we're not using it anymore!"
The real reason that we can't have the Ten Commandments in a Courthouse! You cannot post "Thou Shalt Not Steal," "Thou Shalt Not Commit Adultery" and "Thou Shall Not Lie" in a building full of lawyers, judges and politicians! – It creates a hostile work environment."
