Response to Dom Cooper "Determination and the Legal Process"

I too was pondering this topic, here are a few of my thoughts. I believe the actions that are punishable would remain very similar, however the punishments may be altered in a determinist system. Current consequences involve protecting the public, trying to correct the problem, and just pure punishment. I think a determinist system would really try to push keeping the public safe, and influencing the offender enough that there "determined" future will be safer for society. One more question I thought about it could somebody still plead insanity if everything is determined?
