Kennedy arrived in Boston Thursday from the Kennedy compound on Cape Cod, where one of the most respected an influential senators in American history died late Tuesday. After a private mass, the procession drove past an American flag that flew at half-staff in front of the Kennedy family home at Hyannis Port, Mass.
