Vincent Bugliosi: Lawyer Authored 'Helter Skelter'

BOSTON - MAY 22: Vincent Bugliosi, prosecutor of the Charles Manson case and author of "Helter Skelter," the bestselling book about the Sharon Tate murders, has spent the last 20 years working on a massive book about the John F. Kennedy Assassination. Now the book is done, and it is truly massive: 1,650 pages. Bugliosi concludes that Oswald did it, that he acted alone, and that there was no conspiracy. Bugliosi hopes that the massiveness of his exploration of all the evidence, and his detailed rebuttals of all the conspiracy theories, will finally put the matter to rest.
