This is not news. Somebody shaking somebody else's hand during the giving of the peace at a Pope's funeral is not news. Shaking somebody's hand is not the same as saying you agree with them in anyway, or approve of anything they do. It is merely an acknowledgement of their existence. If I had been in Charles's place, I think I would have just come out and said, look I shook his hand I didn't suck his dick.
This probably is. Was she a drug dealer? Was she an innocent old grandmother? Who knows?
