Unfortunately we all agree to live under this rule of law though. "Innocent" legally only means you weren't convicted, and whether standards like beyond a shadow of a doubt was met is up to the jury and later the appeals court.

I agree the system is terrible, if even one innocent person can be found guilty and punished or even killed then the system is broken in my opinion. We can't fix that one-off though, and targeting one state's use of the death penalty is only going after a more obvious symptom while ignoring the root cause.

While I will always support seeing a person wrongfully convicted go free, I'd much prefer a fundamental revisit of our legal system so we don't have to catch mistakes like that after the fact.
