Witness reliability plays prominently in Troy Davis' internationally-watched case. In the two decades since Davis was condemned for fatally shooting Savannah police officer Mark MacPhail, seven of the nine witnesses who testified against Davis at his trial have recanted their testimony. No jury has heard those recantations, and a Savannah judged looked upon evidence of changed testimony with suspicion.
The Georgia Board of Pardons and Paroles Monday will hear from supporters and opponents of Troy Davis' execution. The state is set to put the condemned prisoner to death on Wednesday for the 1989 fatal shooting of Savannah police officer Mark MacPhail. A UGA Law School professor says, there's too much doubt in Davis' case to carry out an irreversible sentence.
