Demonstrators in major cities, including Chicago, gathered to protest gun violence March 24 as part of the March for Our Lives. The movement is student-organized and is in response to the Valentine's Day mass shooting at Marjory Stoneman Douglas High School in Parkland, Fla. Washington, D.C., was home to the main event while 800-plus other marches were scheduled across the globe, according to the movement's website. Here is a look at some of the protest signs seen at the Chicago march and throughout the country.
