Chicago's Annual End Of The School Year Peace March & Rally

As a young woman speaks from a lectern, March For Our Lives student gun control activists stand on stage during the annual End of the School Year Peace March & Rally in the South Side neighborhood, Chicago, Illinois, June 15, 2018. One wears a 'price tag' on her shorts that reads '$1.05'; the number relates to the dollar amount that the March For Our Lives activists, in the wake of a mass shooting at Parkland, Florida's Marjory Stoneman Douglas High School, calculated their lives were worth to Florida Senator Marco Rubio (based on the amount of money Rubio accepted in donations from the National Rifle Association divided by the number of the state's students). Students from school were among the special guests at the event. (Photo by Steve Schapiro/Corbis via Getty Images)
