The Minuteman Civil Defense Corps was a volunteer group at one time headed by Chris Simcox and dedicated to preventing illegal crossings of the United States border. Arguing that the government is insufficiently concerned with securing the U.S. border, they have organized several state chapters, with the intention of providing law enforcement agencies with evidence of immigration law violations. The group was one of several that emerged for the proliferation of civilian border patrol groups at the US-Mexico border. It is shown that the emergence of these groups can be linked, on the one hand, to an increasing criminalization and securitization of immigration.Simcox states that the group merely reports incidents to law enforcement, and does not directly confront immigrants. There is a standard operating procedure (SOP) that must be followed by Minutemen volunteers. Rules include not speaking to, approaching, gesturing towards or having physical contact in any way with any suspected border crossers they may see. The organization has been criticized as being a right-wing militia.
