Particularly chilling:
In just under half of the exonerations last year, defendants were wrongfully convicted in cases in which no crime was committed. This included more than a dozen drug possession cases, 11 child sex abuse cases and nine murder cases.
In one case, Rodricus Crawford, who was on death row in Louisiana, was exonerated. The state dismissed all charges against Mr. Crawford last year after officials acknowledged that evidence suggested his infant son died with pneumonia and bacteria in his blood, implicating sepsis in the death rather than murder.
