Set in 1974, published by Livingston Press at the University of West Alabama in 1996, Sixteen Reasons Why I Killed Richard M. Nixon consists of sixteen first-person accounts by people who claim to have done the deed. 

The narrator of the book says in the introduction, "I can tell you what's most interesting about them to me.  It's the same thing that's most interesting to the characters who tell the stories.  If you look, every one of these people who claims to have killed Nixon, what they're interested in talking about is not the killing itself, but the reason for it.  What draws them out is not the means of death but the whole moral basis that brought them to the action.  Every one of these people has a cosmology, and has built up a whole ethos to go with it, and is struggling hard to explain it to anyone they can beg to listen."
