When police and prosecutors suppress evidence of innocence in order to obtain and protect a conviction, the innocent defendant isn’t the only victim. The guilty party is left at liberty to strike again. What’s really shocking about the Michael Morton case is the long struggle of the DA’s office to prevent the post-conviction DNA tests that apparently have now identified a double murderer.
American law schools teach the superiority of the common-law adversary system as an article of faith. That’s appropriate. If you had to rely on logic or evidence, you might wind up doubting that competing attempts at flim-flam lead to the truth.
