After Customs and Border Patrol agents shot and killed Alex Pretti in Minneapolis yesterday, the Trump administration immediately branded him a “domestic terrorist.” The specific allegation it employed to support this hyperbolic charge was that, because Pretti was carrying a firearm while filming and then clashing with agents, he intended to massacre federal officers. Even if that were true, it still would not remotely justify the fact that, according to multiple videos of the incident, agents shot Pretti after they had pinned him to the sidewalk and disarmed him.
