 There were also marches and demonstrations, including a march on June 28, 1966, at which over 200 Puerto Ricans from the Division Street area marched five miles to City Hall to protest the city government's negligence and police brutality.A month after the riot, the Chicago Commission on Human Relations held open hearings, which provided a forum for Puerto Rican and other Spanish-speaking residents of Chicago to discuss problems facing these communities.They discussed the displacement and discrimination in housing, discriminatory practices by the police and fire departments, and poor educational opportunities.
