What Is Black Lives Matter? VOA News Attention has been called to the Black Lives Matter movement by Blackout Tuesday -- in which the music and other industries in the United States this week protested the death of George Floyd and other African Americans by shutting down for 8 minutes and 46 seconds -- the length of time Floyd was held to the ground with a policeman's knee on his neck. This statement against racial injustice has largely been associated with the Black Lives Matter movement, which began in July 2013 when George Zimmerman was acquitted of fatally shooting Trayvon Martin, a 17-year-old unarmed black teenager. [1]Martin was killed by Zimmerman as he was walking from a convenience store to his father's home in Sanford, Florida, where he was visiting. Zimmerman, a self-proclaimed neighborhood watchman, called the local police department, mentioned there had been burglaries in the neighborhood, and said he observed "a real suspicious guy" who was "up to no good." The police dispatcher told Zimmerman his security services were not needed, but Zimmerman still left his vehicle, leading to a violent confrontation between himself and Martin. Zimmerman fatally shot Martin at close range and later claimed to police Martin assaulted him and he shot Martin in self-defense, the basis of his acquittal.
