And the opposite is true of the defense. The result is a 3rd party gets to hear all of the evidence either side could come up with and weight the outcome based on all of that instead of 2 interested parties trying to figure it out themselves.

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.
