I never disagreed with the idea that humans should be involved. I was concerned about the use of "responsible".

Let's be specific who you're comparing a judge to though. A guard, social worker, or bureaucrat with the guard being most likely. A guard probably has a lot of things to do on any given day, administrative exercises would only be part of them. The same could be said of a social worker. This is why I cautioned against making someone who is likely underpaid and doesn't have much time capital "responsible" for something as important as how long someone stays in the system.
