I was thinking the same thing. The only time I heard of the Capitol visitors attacking the cops was when some cops were beating some woman who was laying on the ground (or maybe the cops were just pushing more people on top of the defenseless woman) and these people were trying to keep the cops from beating on the woman (who eventually died). So if this cop was one of those who murdered the woman - then yeah, he deserved a beat down. And I'm sure the people that tried to defend the lady are still rotting in DC Gitmo.
We have two justice systems.
There were some photos of stupid demonstrators attacking the police at the barricades in a vicious manner. The question is who was involved.
That said, some of the officers who testified at the congressional witch-hunt hearings sounded like they were trained in how to speak.
Having testified before four congressional committees including one in Executive Session (for security reasons), I learned that most of what you say is in response to the counsel/congressperson’s requests or questions. If you sound too good,it is because you’ve been trained to sound that way.
