Darn! Have you ever heard of anything like this being allowed in court?
No, but at least we can take comfort in the fact that the jurors will also be noticing his mannerisms. I think it's just human nature to get a "feel" for someone's attitude, by watching them while they are talking. I think at least some of the jurors are going to feel doubtful of Scott, the same way some of us do when we see his mannerisms in those videos. Such as his looking away when speaking. That really looks bad.
He should never have given those interviews. He is a total fool for doing that.
