Our “justice” system was arguably designed to allow some guilty people go free in order to prevent innocent people from wrongfully being robbed of their liberty.
Sure, but this doesn't impact my point, which is that relatively few mistakes don't impugn the design system. Other things might impugn it, but a few mistakes don't, that's all I'm saying.
You're right that a few mistakes wouldn't impugn the design of the system, but in this case there is no ambiguity- the US justice system is intentionally evil.
I wasn't arguing that there is ambiguity. Not sure how many times I have to say that in this thread.
