With a single punch, Trayvon Martin decked George Zimmerman, the Neighborhood Watch volunteer who eventually shot and killed the unarmed 17-year-old, then Martin climbed on top of Zimmerman and slammed his head into the sidewalk, leaving him bloody and battered, Zimmerman told police, according to the Orlando Sentinel. Much of it has been corroborated by witnesses, authorities say. Zimmerman says he shot in self-defense.
Civil-rights leaders and more than a million other people have demanded Zimmerman’s arrest, calling Martin a victim of racial profiling and suggesting Zimmerman is a vigilante. Martin was an unarmed black teenager who had committed no crime, they say, who was gunned down while walking back from a 7-Eleven with nothing more sinister than a package of Skittles and can of Arizona iced tea.
