The Georgia Board of Pardons and Parole has denied celemency for convicted killer Troy Davis.
This means he is set to be executed at 7pm on Wednesday.
Davis was convicted of the 1989 murder of a police officer but questions have been raised about his guilt and some of the witnesses have recanted their testimony.
I think this kind of case illustrates my concerns about the death penalty. I have absolutely no empathy for a cop killer, so if Davis is guilty he should be punished. But it does appear there are questions about his guilt and once he is executed you cannot take it back.
On the other hand he has had a number of reviews by both state and federal courts.
