How Far Can Fiction Go?

The Christian Science Monitor has an interesting article about a sure to be controversial new book. Checkpoint, by Nicholson Baker, is a short novella in which two characters argue about whether to assassinate the President. Not a non-name, fictional President, mind you, but one George W. Bush. The book appears to present the would-be killer (doesn't say what the outcome is) as unbalanced and not at all rational. Still, right-wingers are bound to get pissed about it.
