I believe a policeman was killed in one of the Dorhn/Ayers/WU bombings. I am not sure of the total number of persons killed, I think there was at least another incident that killed a chemist at a college lab late at night.
If this production were to be about his parents’ exploits, I think there is some legal basis to go after the profits from the work.
Bombing the Pentagon is a federal crime no matter how you look at it.
And treason is a crime defined in the Constitution. There is no defined prosecution time either. Did Carter’s grand penstroke pardon them all?
