This article from Sunday's Miami Herald is a moving account of the story of James Adams who was electrocuted by the State of Florida in 1984 for the murder of Edgar Brown. Twenty years after Adams' execution there remain serious doubts about his guilt. The entire case was built on circumstantial evidence. Furthermore, according to the article, for every piece of circumstantial evidence pointing at Adams' guilt there was a piece of countering circumstantial evidence that argued for his innocence.
Read the account, I'm sure you'll find the handling of the evidence and the prosecution of the case disturbing. Of course I feel that Adams should not have been executed even if he was guilty. However, the very idea that he might have been innocent makes me extremely angry and fills my heart with true sorrow and regret. Not only might an innocent man have lost his life, somewhere out there is a murderer who watched another man die on his behalf. He's responsible for two murders as far as I'm concerned: Edgar Brown and James Adams.
