I think they would have had to, but then when you see them speak about KC's guilt/innocence they say these things with a straight face, like they really believe what they are saying. I guess it's possible to lie with a straight face if you have enough practice, but it still baffles me how they can say things like "I believe everything my sister has said" and not crack a smile. Especially when sitting in front of cameras, a room full of people. He's pretty good at deception, and it's not too difficult to see where it comes from. I had higher hopes for Lee, but not anymore.
