If flaws were only obvious ones, Alan or another there it would be the same. Anyway the KoH is a good actor able to fascinate "open-minds" of who (like Alan) give him credibility.
I didn't suggest that any flaws would only be obvious ones. And what will be obvious to Alan would not necessarily be obvious to someone without a relevant background.
No doubt Rossi will attempt to wring an ounce of credibility out of any opportunity that falls into his hands.
