Iwao Hakamada, on death row in Japan for a 1966 quadruple murder that DNA evidence now shows he may not have committed after all. Amnesty International named him the world’s longest-serving death row inmate. His confession was apparently beaten out of him at the time.
I’m not opposed to the death penalty on moral grounds, but this case shows why if you’re going to have it, then it should be limited only to those who are guilty beyond a shadow of any doubt, your John Wayne Gacys and the like.
