On the day of the Arizona massacre, Arizona Rep. Raul Grijalva blamed the "Palin express." The father of Gabrielle Giffords, one of the victims, blamed "the whole Tea Party." The sheriff of Pima County, Clarence Dupnik, who had failed to lock Loughner up despite repeated arrests and other contacts, blamed "the vitriolic rhetoric that we hear day in and day out from people in the radio business and some people in the TV business."
