I can’t say I know much about Daniel Friedman, but I don’t get the credence some on “our side” assign to Scott Ritter:
Believe him and his adherents if you like, but some of us aren’t going to kneejerk swallow fantastic allegations without actual evidence, especially when they come from someone who helped the United Nations implement arms control treaties and who was later “found guilty of unlawful contact with a minor and five of six other charges after a three-day trial in Monroe County Court on charges stemming from an online sex sting.”
That said, ad hominem is a logical fallacy. Always look at evidence, including for the credibility of those offering interpretations, inferences, and pronouncements.
