Sure, but by that time, both groups had devolved and shrunk to the level of common criminals. By the mid seventies, they'd both failed in their revolutionary missions. By the eighties, they were a broken shell of their former selves.
I was a young adult at the time, and well remember the events of those days. Hell, the Panthers even tried to recruit me during my high school years.
There was no Weather Underground until fall of 1969.
They were a splinter group from the Communist front SDS.
It is erroneous to associate them with the 60s.
And they didn’t end their activities when the Viet Nam war ended. Ayers figured the revolution they wanted would require the murder of at least 25,000,000 Americans who would refuse re-education.
Just how many persons do you think were ever in the Weather Underground anyhow?
