If Bill Ayers was a "terrorist", who was terrorized?

I'm not defending him.  Bombing public buildings is wrong, and even trying to do it when no people will get hurt is risky -- you might mess up and become a murderer.

But that's not the same as terrorism.  Terrorism is about sowing fear: after 9/11, people were afraid to ride in airplanes or go up in tall buildings.  That's terrorism: people feeling actual terror, which is, after all, part of the point (if you're a terrorist).

Did anyone walk the streets trembling because of this stuff in the 1960s and early 1970s?  I don't get the feeling they were.
