STATEN ISLAND, N.Y. -- New York City Council Speaker Melissa Mark-Viverito at the "We Will Not Go Back" march and rally called by Al Sharpton and the National Action Network to demand justice for the family of Eric Garner whose death was declared a homicide by the NYC Medical Examiner. Garner died on July 17, 2014 while being arrested by police. The ME ruled the cause of death was an illegal chokehold (applied by P.O. Daniel Pantaleo) and "chest compression" - prompting civil rights advocates to organize this very large protest (approximately 4000 demonstrators).
