Scooter Libby got convicted of a crime that Dick Cheney committed. Libby deserved to go to prison, but Cheney and his enforcer David Addington were far more guilty. If our government has an iota of self-respect, it will prosecute Cheney and Addington for myriad crimes, including violations of the National Security Act of 1947.
Yes, I know that it is totally unprecedented to prosecute a former vice-president, but it really is the job of the Justice Department to enforce the laws. Compare the culpability of Dick Cheney to Spiro Agnew, for example. There is no comparison. Compare the crimes of Attorney General John Mitchell to those of David Addington. This is a no-brainer.
