I think some books should be banned. Many books contain bad language that just shouldn't be used in books or otherwise. Some good books, like Huckleberry Finn, are good books, but often have bad words in them. Theme is also a problem. What if someone wrote a book about terrorists who bomb the White House. Mabey the book has a great plan of how to do it, something that would work. You can't just give people a fool-proof plan on how to kill the president. What if someone wrote about a new form of government that sounds appealing. New theories about how the USA should be run would rise. Despite the freedom of speach, some books should be banned.
