I think Karr just said that cause that is what he wants his defense to be. He knows good and well this wasn't an accident, but he is trying to save face and if he really did do this crime he is going to try to make himself appear a bit better to prevent getting the death penalty or more time.
I think if he is charged and found guilty and the judge does not give him the DP, I will be outraged.
Certainly, he could say it in a written confession but by that time, attorneys would have told him not to do that. How do you "examine" it. Do you turn it into an insanity case??
Do you just let him plead out 2nd degree and get away with "murder" in the first??
It eliminates a trial. Despite all his "communications", I don't think this guy wants a televised trial. He's got Unabomber mindset.
But I think the Ramsey family deserve all the truth that can be extracted from him and if there is any possibility that he has harmed others.
A trial should be mandatory...No plea!!
