Threatening to commit mass shootings

This article reports over 40 people arrested around the country over the last month for threatening to commit mass shootings or bombings, most after tips from the public. Common themes included right-wing ideology and threats against schools, Walmarts, and Planned Parenthood. The nature of the cases ranged from “vague social media threats from juveniles that set parents on edge to well-developed plots from people who had access to weapons and appeared to authorities to have been planning a mass murder.”
