The evening after Chicago's first Puerto Rican Day parade, allegedly in response to a call about a group of men fighting, police began a foot chase of two of the suspects. An officer shot one of the young men in the leg, which sparked a rebellion in the Puerto Rican community, not only against the police brutality in that moment but to long simmering frustrations with structural inequalities. Here, police arrest a young person during the rebellion, near Hoyne Avenue, Chicago, 1966.
