By Mark Scolforo(AP) Philadelphia's top prosecutor and the state district attorneys' association are staking out opposing positions in a case to determine if Pennsylvania's death penalty will remain in effect. Philadelphia District Attorney Larry Krasner said July 16 his own review found the state's death penalty runs afoul of the prohibition on cruel punishment and disproportionately applies to black defendants and the poor. The Pennsylvania District Attorneys Association also filed a brief with the state Supreme Court, saying the justices should respect the Legislature's role in establishing state law. The high court in December took a pair of cases that will decide if the capital punishment system violates state constitutional protections. Two death row inmates argue arbitrary factors determine who gets sentenced to death. The Supreme Court will hear the case in September.
