A New York judge on March 19 denied the motion to dismiss a lawsuit against several social media platforms that alleged they contributed to the radicalization of Payton Gendron, the gunman who killed 10 people at a grocery store in Buffalo, N.Y. in 2022. The lawsuit, which was originally filed in May 2023 on behalf of the families of three victims, claimed that the then-18-year-old was motivated by the “psychological vortex” of “social media applications” and “fed a steady stream of racist and white supremacist propaganda.”
