The point here is that as you stated: "you still do not understand". For those of us that have been under the thumb of the judicial system it can feel like the world is on you. We have no idea of his mental state, we have no idea of the nuance or motivation but what I do think we know is that the actions of the state here far exceeded any interpretation of what would be deemed an appropriate punishment for the said "crime" committed. What we do understand is that if he hand not been attacked by an over-zealous prosecutor there is a far greater probability he would have been able to handle the situation in a logical manner and maybe even still be here today to defend himself.
We are not asserting that any specific outcome is empirically superior to another just that given the facts of the case, it was not adjudicated fairy given what we know of similar cases.
