Two top officials of the anti-immigrant group Minutemen American Defense have been arrested on murder charges in Arizona. Shawna Forde, the group’s executive director, and Jason Bush, the group’s operations director, were both charged with two counts of first-degree murder. A third person was also charged. Police say the three broke into a home and killed a man and his eight-year-old daughter. The Minutemen American Defense organization has sent teams of armed vigilantes to the US-Mexico and US-Canada border in an attempt to stop undocumented workers. It is a separate organization from Jim Gilchrist’s Minuteman Project.
