I was very sad to hear of the execution of Troy Davis. He had been convicted in the killing of a police officer. EVen though many jurors who had originally convicted him have changed their mind on his gulit, many witnesses who testified against him later recanted their testimony, the murder weapon was never found, and no physical evidence at all was found connecting Troy Davis to the murder/crime scene, he unfortunately was executed last night. I don't know enough about this case to make an educated decision as to whether he is the real killer or not. I do know however, that enough reasonable doubt existed that should have prevented him from being executed last night. While the family of the slain police officer remains convinced the true killer has finally been served justice, many across the globe believe an innocent man was executed. This is the problem I have with the death penalty. It's used in cases where reasonable doubt exists, possibly putting the wrong person to death. It should only be used in cases where absolutely no reasonable doubt exists.
