Many people are talking in where is the advantage.
Maybe there isn't. Maybe he just doesn't like the farce, and it's tired of all the stupid lies to take personal profit.
May he thinks: "I did it and I'm just going to say I did it, that's the truth and I'm not going to lie for personal benefits".
O maybe not. Maybe I'm just projecting my own apathy towards this insincere world in where everyone always lies to get personal gains.
I already had great respect for the guy, if this was the reason, just not wanting to lie, my respect for him will just go through the roof.
He should create the department of "delay, deny, depose".
