DNA and the Death Penalty

  • Professor Brandon Garrett discusses the strengths and weaknesses of DNA as evidence. DNA offers a high degree of certainty in the cases where it is available, but in many cases, like that of Troy Davis, the DNA evidence just isn’t there. Individual exonerations are nonetheless suggestive of a wider pattern of wrongful convictions throughout the criminal justice system. It is difficult to say how large this pattern is, but DNA evidence has certainly made us aware of certain problems that existed prior to its use. Does this increase or decrease our faith in capital punishment? And where will public opinion settle?
