Far right points to lax criminal justice system and racist narratives, not mental health system failures as experts say

The random and unprovoked killing of a young woman in North Carolina several weeks ago has become a viral video, a political football, and a powerful rightwing talking point – even as the horror and anger her death has provoked obscures what experts say is a vital story about the failures of the American mental health system.

The alleged perpetrator, Decarlos Brown Jr, 34, has a long history of problems with the law and mental health issues. He had been arrested 14 times and served a five-year stint for armed robbery. Brown had also come to believe that there was something alien and malevolent inside him – a “man-made material”, he told people, possibly a computer chip implanted by the government that was fighting him for control of his body.
