This is just a sick, scary, amazing story of a man who came within days of execution because prosecutors knowingly withheld exculpatory evidence. And not something arcane and equivocal, but blood tests that were the wrong type and witness testimony that contradicted the main witness.
The Supreme Court has upheld the effective immunity of prosecutors from any penalties for not following the most basic rules. Forget sanctions or lost law licenses - why aren't these prosecutors on trial for attempted murder? Obviously, with the Supreme Court decision a legislative solution is required, but don't hold your breath -- there is nothing more bipartisan than being "tough on crime" when running for re-election so it is unlikely any safeguards of defendants will be improved.
