A reveler, right, shakes the hand of a police officer as a crowd made its way toward Boston Common after the final suspect in the Boston Marathon bombing was arrested, Friday, April 19, 2013, in Boston. Marathon bombing suspect Dzhokhar Tsarnaev was captured in Watertown, Mass. The 19-year-old college student wanted in the bombings was taken into custody Friday evening after a manhunt that left the city virtually paralyzed and his older brother and accomplice dead.
