If the SDS were involved, then violence was a high probability. IIRC, Bill Ayers and that b!tch Bernadine Dohrn had several ties to it as well as founding the Weather Underground.
Further, if I also recall correctly, Ayers was present at a meeting of minds in which the execution of upwards of 20-30 million citizens (who would not conform to their ideology would have to be undertaken) was actually earnestly discussed.
Funny how often Bill Ayers was always nearby when there was violence in those years.
