In the wee hours of the morning, when President Trump predictably dumped a truck worth of gasoline on the volatile situation in Minneapolis, Twitter took the extraordinary step of hiding the tweet with a disclaimer saying it violated rules against “glorifying violence.”

There shouldn’t be much debate that in the midst of a riot in a major American city, it is beyond atrocious for Trump to tweet “when the looting starts, the shooting starts” in the context of talking about sending in the military. And, as a private entity, Twitter should be allowed to set whatever rules it wants for policing content, even if it applies those rules arbitrarily.
