The flip side:

Can you look someone in the eye who was falsely convicted of a crime and spent over 20 years in prison and tell him that you think the system worked just fine in his case? That it worked too hard in fact?
I look at the last 20 years of my life and think of what happened: I met my now husband who I love more now after 18 years together; I've had several dogs who were the light of my life; I had a career that filled my spirit with joy; I watched my siblings' three children grow up and earned my status as the crazy auntie; I spent my mother's last days on earth at her bedside holding her hand, including the moment she died. More things happened than I can possibly list and none of them would have happened had I been unjustly incarcerated.
There is nothing, absolutely nothing that can make such a loss good again.
The Department of Justice estimates that 3-5% of the people in prison today are falsely convicted. Since the vast majority of those cases do not involve DNA evidence, those people serve sentences that they did not deserve with no relief possible. At the low end of the estimate, that is 60,000 people in jail, losing parts of their lives that can never be given back to them.
