Families react to ruling that Davis should get new evidentiary hearing

The U.S. Supreme Court ruled Monday that an evidentiary hearing should be held in the Troy Anthony Davis case.  The High Court ruling that a federal court in Georgia should review whether there is evidence now to indicate that Davis is innocent.  Davis supporters say in recent years, seven of nine witnesses who named Davis as the killer at his trial in 1991, have now changed their testimony, saying he isn’t the man they saw the night that Savannah Police Officer Mark MacPhail was murdered.
