Query: What a hack this guy is...

Truth, what is truth? If you'd like to know the answer to this question, don't ask Graysmith because truth is not apparently important to him. It also does not seem a requirement for journalism in his eyes. All of Graysmith's Zodiac theories twist or disregard facts in order to point to a non-suspect. Allen was not the Zodiac and anyone who has researched the case and has even one fourth of a brain can see that.You know how when a six-year-old is caught in a lie and they can't admit it and they just keep saying "Nu-huh," this is what this book is to me.
