Death penalty opponents say, they hope the execution of Troy Davis will be the catalyst for a renewed fight to end capital punishment in the U-S. Davis' defenders tried to put the most positive spin on a failed 20-year attempt to overturn the Savannah man's conviction and sentence. Amnesty International Director Larry Cox says, his group's effort to abolish the death penalty will start again.
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.
