On Saturday, the FBI arrested the leader of a vigilante militia group that has been holding border crossers in southern New Mexico at gunpoint. But as of late Tuesday, videos of such apprehensions conducted by his group, United Constitutional Patriots, are still available to view on Facebook, despite apparently violating the company’s content policies. The disturbing videos depict the group’s vigilante border patrols, and show seemingly armed members stopping, questioning and turning over migrants—often including families with small children—to the US Border Patrol. Change the Terms, a coalition of nonprofits and civil rights groups pushing tech companies to work to reduce hate online, published images of the videos on Twitter on Tuesday, and called for Facebook to take them down.
