For another stunning account of actual innocence and "justice" misfiring, don't miss the Louisville Courier-Journal story of Michael Ray VonAllman's eleven years behind bars for a rape he did not commit. The details of this miscarriage of justice are well-told by Jason Riley, and I will not detract from the narrative by abstracting from it. It should be read in its entirety.
What I find moving in these innocence project examples is the freedom from bitterness these men and women have after decades, in some cases, spent behind bars after wrongful conviction. More importantly, look at how "evidence" of guilt is frequently wrong, eyewiteness testimony is unrelaible, and what seems damning proof is distorted by prosecutors, law enforcement, judges, and jurors through bias.
