Obama's Books Damage National Security?

In what is surely the goofiest story of the month, Federal Prison authorities have denied access to two books authored by President Obama to al-Qaida member Ahmed Omar Abu Ali, who is serving a 30-year sentence at the federal supermax prison in Florence, Colo. The Associated Press report is here. Apparently, the prisoner requested access to the books last year, and based on FBI "advice," prison officials recently denied the access, because "passages in both books contain information that could damage national security." The prison system referred inquiries to the FBI, which was "looking into" the situation Thursday (7/9/09).

This is the kind of thing that gives bureaucrats a bad name. I wonder if this means that anyone who reads the President's books could damage national security, or if it's just convicted terrorists that are causing concern? It seems that if prison officials simply wanted to make the prisoner realize he's in the "supermax" federal prison and should not be enjoying reading books, citing national security was serious overkill.
