BettyHumpter: Still why would you even include that?
I'm thinking that there are a couple of reasons:
1. He can't help himself. As you noted, He seems incapable of leaving well enough alone and giving concise answers. I think he wants so desperately to 'win' every interaction he has, that it frustrates him if he only gives a short answer. The fact that giving more information just gets him into more trouble doesn't occur to him, because he seems convinced that he's the smartest guy in the room.
2. Some of the damning evidence against him is the pictures on his own phone, which his wife apparently sent to someone else, who then posted them publicly. Who knows how many other photos (or possibly video) might be just a button click away from showing up online? I think he's trying to stay ahead of the issue just in case any more embarrassing content becomes public.
He won't listen to good advice because the only person he trusts is himself, and he is turning out to be so UNtrusthworthy that even that is turning out to be a mistake.
