In 2012 Trayvon Martin was shot and killed in Sanford, Fla., by neighborhood watch member George Zimmerman. Martin, a 17-year-old African-American high school student, was visiting a friend with his father and was unarmed. Based on Florida's Stand Your Ground Law, Zimmerman was acquitted of second-degree murder, claiming he shot Martin in self-defense. The fatal encounter and the subsequent trial sparked outrage and protests and shined an unforgiving light on issues including race, politics, power, money and gun control.
