It is corrupt extraction of human ability and based on suffering, it is just not tracked closely. People do time for the worst things. Using drugs is not a real crime worthy of punishment, for example, but people just sit and sit and work and work for really dumb stuff like that. Justice system seems clearly not some rehabilitative thing where people involved are helping in good faith. That is maybe what they imply on tv crime shows or something.
If public defenders get better, the canonical theory is that the prosecution will be forced to make stronger cases with better evidence, improving the criminal justice system overall.
However, if the number of falsely accused people weren’t high in the first place, there shouldn’t be a significant drop in convictions if the prosecution cab keep up. If they can’t , then presumably crime rates would increase and there would be public pressure to increase funding for police and prosecution and less funding for public defenders, and then you’d end up where you started
The prosecutor has a much bigger influence on outcomes than a public defender.
What? Why?
Public defender might help the innocent stay free. But if you actually did the crime and were caught you're probably still going to jail barring some impropriety being involved.
