Any suspicions about the Warren Commission and its findings should be allayed by Vincent Bugliosi's 1,600 page investigation called "Reclaiming History" (2007).

There's an abridged version on CD that presents the gist of it. Very listenable.

Bugliosi was prosecutor who put away Charles Manson. His book reveals the incredible amount of misinformation, confusion, error, distortion, illogicality, cherry-picking, and outright fantasy to be found among the conspiracy theorists.

But not in the Report of the Warren Commission, which Bugliosi also goes over with a fine-tooth comb.
