In response to the Festival of Life and other anti-war demonstrations during the Democratic convention, Chicago police repeatedly clashed with protesters, as many millions of viewers watched the extensive TV coverage of the events. On the evening of August 28 the police attacked the protesters in front of the Conrad Hilton hotel as the demonstrators chanted "The whole world is watching". This was a "police riot," concluded the US National Commission on the Causes and Prevention of Violence, stating:"On the part of the police there was enough wild club swinging, enough cries of hatred, enough gratuitous beating to make the conclusion inescapable that individual policemen, and lots of them, committed violent acts far in excess of the requisite force for crowd dispersal or arrest."
