Sounds like a heck of a read. And a great purchase to get you on a list. Pay cash. Ashcroft hates that.
Christian Science Monitor: "Checkpoint"

A work of literary fiction, it carries Michael Moore's case against Mr. Bush to extremes that the partisan moviemaker has never dared
approach. It may also be the most specifically articulated argument about killing a sitting US president ever published by a major commercial
publisher.
"Checkpoint" reads like an attempt to exorcise anger at Bush's international policies, but in a phone interview from his home in Maine, the author
says, "No, this is a book about the rage and sadness of war, and about the moral consequences of war, boiled down to a conversation between two
people. I want readers to think things through. Sometimes a novel is the best way of making that happen."

Raving and enraged opinions of the content aside...is this legal?
