If Chris ends up going to actual prison and not some state mandated home for the criminally autistic, I will have to say the probability of him actually surviving prison is closer to 15-20 percent. With the odds getting worse longer the sentence is. Knowing Chris and his nature, likely he is going to be a very disruptive prisoner. Unlikely good behaviour is in the equation and more than likely he will end up in some form of isolation or PC because of his charges.
It's unlikely that he is going to provoke other prisoners, more than likely whatever incident of him breaking jail house rules will be against one of the corrections officers. Once Chris is in, I find it very unlikely he is going to get out. Following the rules and respecting authority is an attribute Chris doesn't possess. He will either be in there until he is old and senile, or else he will end up becoming a hero. I go more along the lines of him being old and senile, because he is too much of a narcissist.
