I’m guessing that, as a guy who is accustomed to being right, he felt like he was going to be easily validated. That’s one of the dangers of that style of confidence.The irony is that he thought he was enhancing his reputation, instead he trashed it. Been there. Done that. In many situations, it is much better to just walk away from accusations, and let the reputation of the accuser, and your historical reputation, and your actions, all speak for you.
