You're missing the point. If the info that was provided to Congress was erroneous heads should roll. Bush is President, the HEAD HONCHO. He is ultimately responsible for the info that was supplied to Congress.
If they Admin Lied: If there were known false and/or misleading statements, and/or known material omissions made to Congress in the "case" the Bush Admin presented for war, then that's a very, very "high crime". Again, Bush is President, the HEAD HONCHO. He is ultimately responsible for the info that was supplied to Congress - by whatever source....
Personal responsibility would be a beautiful thing in gov, as in life... And only so much "buck passing"
will actually pass the "giggle test"... And you asked before if I believed it was possible the crew lied, and the answer is... Absolutely!! :)
