So you find out someone is a felon. Before judging, ask. You may find that it isn't as it appears.
This is from the False Justice fb post from today.

DNA was first used in a U.S. criminal case in 1989. It not only became the most reliable form of criminal evidence, but it also delivered a stunning surprise: Innocent people have been wrongfully convicted and imprisoned for years, even decades, in greater numbers than ever imagined.

Why would a book on an Ohio attorney generals rude and troubling awaking to wrongful conviction have relevance in China? The lessons of DNA continue. Among them is that wrongful conviction has no national boundaries. We have yet to fully understand the nuances of wrongful conviction in other countries and criminal justice systems. But there are enough similarities in the contributors, harmful misconceptions, flawed practices, and recommended "best practices" that, remarkably, a book written in Columbus, Ohio, is finding a caring and kindred audience on the other side of the world.

Now consider all of the convictions where there was no DNA, only an accusation? Those convictions will never be over turned. How many are there?
