San Bernardino County District Attorney Michael A. Ramos joined three former California governors in Los Angeles Thursday to announce the start of a signature-gathering campaign aimed at getting a death penalty reform initiative on the November ballot. “I refuse to back down in this fight as we move to bring about common sense reforms to our state’s broken death penalty system,” Ramos said as former Governors George Deukmejian, Pete Wilson and Gray Davis looked on. “We must continue to fight for the families who lost their loved ones at the hands of California’s most violent criminals. For them, the pain never ends.”
