I agree, SixOfNine, with your comment that Longo's logic is impeccable. I think that he would have a chance with the jury if he wasn't such a completely unsympathetic amoral creep.
His story falls apart as soon as you get to the part that goes, "...so I killed them all so they would have the hope of paradise, then I took off for Mexico so I could bang a german tourist gal."
I don't know if Oregon offers the death sentence, but if it does, I hope he gets it. Then HE can sleep in HIS grave "awaiting the resurrection."
