Because there has to be time for the case to be investigated, reinvestigated, investigated again, and of course, America’s Endless appeals system. A death row inmate spends enough time on death row for there to be sufficient cause to believe that they are, indeed 100% guilty of the crime they were convicted of, even if there is outstanding evidence that they did it, like this case.
