Troy Davis was executed last night. All indications are that there is significant room for doubt as to his guilt. He was convicted solely on the basis of nine separate eyewitness testimonies, seven of which have retracted their testimony. Of the other two, one has remained completely silent since the trial, and the other is an odds-on favorite for the actual killer. This is what we knew, prior to injecting him with a life-taking chemical. If this is what we had known prior to his conviction, he would not have been convicted in a legal system that relies on a “reasonable doubt” standard. If there is no reasonable doubt in what we now know, then the words “reasonable” and “doubt” don’t mean what I learned in law school.
