The last tweet Anthony Hill sent read, “Never say never.” Two hours later, around 2 p.m. on March 9, he was shot dead. Reports and video footage, captured moments before his death, spotlight Hill’s erratic behavior: the 26-year-old Air Force veteran had been wandering The Heights apartment complex naked, crawling on the ground, knocking on doors, and hanging from a balcony. When approached by Dekalb County police officer Robert Olsen, Hill charged the officer despite Olsen’s pleas for him to stop. Though Olsen, who is a seven-year veteran of the police force, was equipped with a taser, he fatally shot an unarmed Hill twice.

Today, in response to the Friday night killing of unarmed black teen Tony Robinson by Wisconsin police, nearly 1,000 high school students marched the streets of Madison in protest, and stormed the state capitol demanding justice. "This is what democracy looks like," they shouted.
