Track down the cops that manhandled the senator and arrest them. What they did was very serious, and very much against the law and the Constitution. These stern letters, proclamations and hearings will do nothing to stop this. MAGAs only know action and intimidation. Beatings, gassings, We will not stop them until we start using their tactics against them. and peaceable resolution be damned, because they see peace as weakness.
They see they can ignore the laws and get away with it. They suffer no penalties for breaking the laws. They know how to manipulate the legal system to avoid punishment. They say a governor should be in jail, they arrest a Congressperson, they stop Congress people from doing their duty (inspecting ICE facilities) and they indict them for it. Now Marines are arresting US citizens, breaking their own military oath. And they lie constantly.
I believe this will wind up like Kent State, the Freedom Marches and the Chicago riots, with Trump acting like a dictator, and law enforcement right behind him. The June 14 demonstrations will set the course - and it will have to be the people who rid this country of its wanna be king and his bunch of fascists..
