it is always a tragedy when a truly innocent person is wrongfully convicted of a crime. that means that there is a criminal running loose, free and clear, while another sits in prison for something that they didn't do
What the hell is going wrong with the justice and evidence system?
The overturning of "old" convictions is perhaps understandable. But a few years back our local paper carried a story of a man who spent several months in custody awaiting trial for an alleged "stranger rape". His parents spent their own money getting forensic proof that the accuser had in fact been to his flat - she convicted of wasting police time or something and was sent to jail (though I think she spent a shorter time inside than he did).
I was disturbed to think that the police had not even bothered to investigate his version of events.
