On his show Hardball, Chris Matthews really bored into one JFK assassination proponent (whose name I can't recall) about Oswald's job at the School Book Depository. The guy couldn't answer the question.
One thing Bugliosi does well is showing how many assassination theories actually cite evidence from the Warren Report, but merely exempt or call into question (or just plain ignore) anything that contradicts that.
A big example, he notes, is when conspiracy theorist will bash the FBI evidence in one sentence, and then cite and FBI report related to the assassination as reliable evidence for something...
