In 1995, Arpaio reinstituted chain gangs. In 1996, he expanded the chain gang concept by instituting female volunteer chain gangs. Female inmates worked seven hours a day (7 a.m. to 2 p.m.), six days a week. He also instituted the world's first all-juvenile volunteer chain gang; volunteers earned high school credit toward a diploma. One of Arpaio's public relations actions was the requirement that inmates wear pink underwear in order to prevent its theft by the released inmates. He claimed this saved the county $70,000 in the first year the rule was in effect. Arpaio subsequently started to sell customized pink boxers (with the Maricopa County Sheriff's logo and "Go Joe") as a fund-raiser for Sheriff's Posse Association. Despite allegations of misuse of funds received from these sales, Arpaio declined to provide an accounting for the money.
