To a degree, I get your point. But the primary concern in both Stone and Trump’s cases was the destruction of documents. I didn’t see either situation as being one where violence was expected.
If the SWAT team showed up in Sean Dunn’s case because they, too, were concerned about a destruction of documents, than I think you would have a case here. As a show of force, however, it adds a layer of absurdism to an already absurd situation. While throwing a sandwich at a police officer isn’t the same as giving them a flower, it also was about as comical an act of “violence” as can exist. It’s almost slapstick. That he did it, knowing full well that the action would cause no actual physical damage to the officer, but also that the personal consequences would be severe, is significant.
