anyone with an opinion. >> everyone around here should be sounding the alarm about this fascist regime in the white house. >> reporter: the only problem, making sure that their voice would be louder than that of the person next to them. >> let's have a meaningful dialogue. he doesn't have any intelligence. >> reporter: based on the overwhelming presence much berkeley police, anyone damaging or disruptive intentions would have been discouraged by riot gear and blockades and block to crucial buildings. at least to outsiders. do you like having your campus become a magnet? >> i don't. if it gets stuff done, i'm happy to share the open space as long it us didn't turn into complete violence. >> reporter: and looking back live at u.c. berkeley now on plaza, looks like a busy afternoon day
