There are huge swaths of people doing the work required to make it better, every day. It's not as easy as turning a dial from "bad" to "good"
surely you don't actually believe that? I don't think the result of this is just 0 false positives. The result of that is a lot more crime, and a lot more injustice.
Or what basically every prosecution does, when it knows that the science behind some things isn't airtight but still presents it in the best possible light to get a conviction.
Unless the person above is, of course, an anarchist who has no answer for what to do about Richard Ramirez, Ted Bundy, Jeffrey Dahmer, Phillip Garrido, or Brian Mitchell. I would say that as imperfect and heavily flawed as our system is, "Perfect is the enemy of good."
Prosecutors in America have one goal: close the case. At any cost, close the case. They are not interested in justice. They are not interested in finding the one who actually committed the crime. They are interested in closing the case. If that is “working as designed”, then we need to change the design.
Nothing. Those people are one-in-a-million anomalies. If it weren't for the media hype surrounding them, their impact on society would be comparable to the impact of deaths from lightning strikes. What do we do about people being struck by lightning? Nothing.
There are of course ways to improve the legal system, more equal access to quality representation is my preferred improvement regardless of system, but you can't just look at one element of the system in isolation and declare the whole concept bad. That's "The CPU produces waste heat so we need to remove it completely" type logic where you find one thing that sounds unambiguously bad and ignore that it could be a symptom of great net positive function of that thing. Doesn't mean it's perfect either, just means it needs more than a shallow dismissal.
