Query: What a waste of time

This is a good read if you want to know exactly who the Zodiac is NOT, Graysmith's suspect has been debunked. Not just by people who "didn't like his book", but by fingerprints and DNA evidence. Graysmith will still try to sell you on Starr (aka Allen) as a viable suspect but can not do so with facts. I'm hoping the upcoming movie wont be quite as fictional but it most likely will be.
