Watch his body language in this interview. A few tell tale signs he's holding something back. He keeps putting his hand on his mouth and chin...as though he's trying to "hold the lie" back. He's almost trying to "scoop" the words he said back into his mouth.
He sits with his legs crossed, as though he's trying to appear relaxed...yet he keeps his hands in his lap all the time, trying to keep his body small. It's not natural, and something you tend to do when you have something to hide.
Sometimes he actually looks proud of what he's done. The smirks, the non-verbal communication all show he's not really sorry. He also talks in the third person a lot. Not a lot of "I" or "me" statements.
Does he seem like a man that is truly sorry?
