Was Arthur Leigh Allen the Zodiac Killer?
A man who runs behind a car gets exhausted.
Absolutely not. There's a good reason why the Zodiac's fingerprints, palm prints, eye witness descriptions and handwriting don't match Arthur Allen's and that reason is Allen isn't the Zodiac.
The movie, Zodiac, and the 2nd book by Robert Graysmith are loaded with outright fabrications to make you think Allen was the killer. The second book, Zodiac Unmasked, is practically one lie right after another. Neither the movie or the 2nd book would have been made/published except that the Supreme Court had previously ruled in another case "you can't libel the dead." Arthur Allen had died years before the 2nd book or movie had come out. The first book uses a pseudonym for Allen and is not focused on him except for one chapter that appears late in the book.
