Here is a picture perfect reason why the US should never have a death penalty. We have no idea whether people committed crimes or not. Here is the story of a simpleton who was twice convicted of -blam!- and murder, and sentenced to death on both occasions. Recent DNA testing showed the culprit was actually a serial rapist who lived a block from the crime. Even knowing the rapist lived nearby, DAs and courts refused to ever hear evidence to overturn the conviction of the innocent man.
