NYC Authorities Confiscating Books!?!

According to this live journal entry, it seems that New York authorities are not only searching the bags of people traveling on public transportation, but they are also attempting to confiscate books they don't approve of! We're not talking terror manuals or anything like that. According to the above post, the officer tried to confiscate a copy of Exalted: The Abyssals because he felt it was somehow "inappropriate". Only after the book's owner threatened to call the ACLU did the officer allow the person to board the ferry with his book.
