AI is fuelling a new wave of border vigilantism in the US

In Arizona's borderlands, the desert is already deadly. But for years, another threat has stalked these routes: Armed vigilante groups who take it upon themselves to police the border – often violently, and outside the law. They have long undermined the work of humanitarian volunteers trying to save lives. Now, a new artificial intelligence platform is actively encouraging more people to join their ranks. ICERAID.us, recently launched in the United States, offers cryptocurrency rewards to users who upload photos of "suspicious activity" along the border. It positions civilians as front-line intelligence gatherers – doing the work of law enforcement, but without oversight.
