Have you read Mylroie's The War against America and Bush vs The Beltway? Perhaps you didn't find Mylroie persuasive because you have already made up your mind and are just seeking those who agree with your preconcieved version of the "truth." What was Hayward's contention?
Also, please look at the endnotes in "1000 Years for Revenge" by Peter Lance, who examines Davis's evidence and, ultimately, discounts it. You'd have to read his analysis---and he's hardly someone looking to "cover anything up." But I will order Davis's book right away.
Lance carries his own baggage. I don't trust anyone who worked for ABC as a reporter. Read this 2003 interview by Amy Goodman with Lance and Minter
LS had it wrong about Lance.
In the course of his investigation, Lance revisits the bombing of the Oklahoma City federal building by Timothy McVeigh and Terry Nichols, and he finds "a growing body of evidence" to suggest that Ramzi Yousef may have designed that truck bomb. He devotes a chapter to this possibility, citing potential connections between Yousef and Nichols (who was married to a Filipina). It also emerges that Murad -- Yousef's co-conspirator -- claimed responsibility for the 1995 Murrah Building bombing on the morning it happened. An FBI document confirms it. (Full disclosure: I've spoken to Peter Lance several times, after first hearing about his work-in-progress from a whistle-blower group that champions FBI reform.)

Boy, talking about having your mind made up already.
