Troy Davis executed after the Supreme Court rejects his eleventh-hour plea

Troy Davis, whose case drew international attention and became a focus for death penalty opponents, was put to death by lethal injection in Savannah, Georgia last night.

Davis, who was convicted of killing an off-duty Savannah police officer 22 years ago, filed an eleventh-hour plea Wednesday asking the United States Supreme Court to stop Georgia authorities from executing him.

After a delay of more than three hours, the Supreme Court issued a ruling denying his request.

Today on American Morning, Paul Callan, CNN legal contributor, explains if he was surprised at the Supreme Court's decision and weighs in on whether or not the protests over Davis' execution will cause reform to the judicial system.
