The protests are designed to bring attention to the recent grand jury decisions to not indict the officers who killed two unarmed black men: Eric Garner of Staten Island, New York, who was placed in an illegal police chokehold; and Michael Brown of Ferguson, Missouri, whose death in August triggered protests and riots in St. Louis and throughout the nation.
Others recently killed by police include 12-year-old Tamir Rice, who was shot for holding an airsoft pellet gun, and John Crawford III, who was gunned down in a Walmart while holding a toy rifle.
