Honestly...IF the impartiality of it all could be taken out and a more "black white" type system could be put in place, perhaps quantification of "extenuating circumstances" for instance? Then sure why not?
Currently the system is broken because of prejudice. You can have two people with the EXACT SAME set of circumstances and depending onthe judge they could receive drastically different sentencing.
What's the worst that could happen?
I don't know that i'd be ready to hand over death or life sentencing to a robot though
