The release of the new report (for year 2013) by the National Registry of Exonerations was recently posted on the WCB by Nancy Petro. See her post here, which includes a link to the full text of the new report.
I’d like to reiterate that the most significant value of the Registry is that it provides hard, verifiable data on which reforms to the justice system can be based. And anyone who studies this data can see that reforms are, indeed, sorely needed.
One of the things I find most interesting is the data that sorts out the major contributing factors to wrongful convictions. This is a very good indicator of both the need for reform in general and the specific areas that are most ripe for reform and improvement.
I encourage you to dig through the full report on your own, but for your convenience, I’m attaching the data on major contributing factors to wrongful convictions for both years 2013 and 2012 below.
From the 2012 NRE report:
From the 2013 NRE report:
Note that for each class of crime, the numbers add to more than 100%. This is because any particular wrongful conviction can have more than one contributing factor, which they most often do.
