Therein lies the problem. The standards of proof you bandy about are used in a court of law. Freeh was not and is not a court of law. He was hired in a private capacity and in a grandstanding press conference accused several people of criminal acts. But I'll play your game and refer to the standards of proof you're playing with. To the best of my knowledge the standard of proof in a civil case is a preponderance of the evidence. In a criminal case it's proof beyond a reasonable doubt. Freeh accused people of criminal conduct yet he (and you apparently) is trying to use the civil standard of proof to show he's right. That's pretty dumb for a guy who is/was a judge. Maybe he'll explain his reasoning when he fulfills his promise and arrives on the Penn State campus to answer questions.
But Freeh even fails to meet that standard.
It's such a complete failure in that regard that I'm sincerely curious if the author of the conclusions/executive summary was prevented from having any contact with the author of the 267-page report.
