A key issue of those hearings was federal law enforcement killing civilians.
Federal agents stated to the Congressmen and all that they had the duty and right to take any necessary action against a citizen before any illegal act was committed -- including killing them. They just needed the suspicion.
I remember my reaction to hearing that -- at least that is how I interpreted the testimony. I don't think I misunderstood but of course that is possible. I have no doubt about my memory for I remember my reaction clearly.
The FBI agents who murdered innocents at those events were branded a hero.
