I have just come up with an idea
Misscaradges of justice are a very srious problem, yet we cannot just get rid of the justice system.
(i think its safe to assume that both of these statements need no explanation.
with that in mind......
How about in cases where a person is sentenced to long jail terms a hearing is required periodically (i wont state how often) whre a new jury hears their case again.
if the new jury convicts the sentence continues (and the same process happens again at the end of the period).
if the new jury fails to convict then the sentence ends.
This would not compleatly solve the issue of wrongfull conviction, but it would greatly reduce the amount of harm done.
