When former Secretary of State Dean Rusk arrives at the Memorial Union for a speech to the summer session of the graduate school of banking, there are no university or city police at the Memorial Union present — even though the Young Socialist Alliance and other radicals had publicly vowed to disrupt the event. Which they do, about 200 demonstrators shrieking invective, and pounding on the theater doors, forcing Rusk to stop twice. It’s worse afterwards. When Rusk is spotted leaving through a rear service entrance, his car is pelted with a half dozen stones and a large stick. Then protesters swarm up Park Street to University Avenue, partially blocking traffic in front of Chadbourne hall for about half an hour, pounding hoods and cursing men trying to drive through as “fascist bloodsuckers.” Radicals scatter on the arrival of Madison police, who make no arrests.
