The United States is experiencing a level of left-wing political violence not seen since the early 1970s, with one key and chilling difference: Today, a radicalized violent extremist can be anywhere. In the past year or so, we have seen the assassination of Charlie Kirk in Utah, two near misses for President Trump, the killing of UnitedHealthcare CEO Brian Thompson in New York, the church shooting in Minnesota in which a transgender assailant allegedly killed two children, and, this week, the killing of two detainees at a Dallas U.S. Immigration and Customs Enforcement (ICE) facility.
