More than 1,000 protesters gathered in New York City's Union Square area on Sunday to protest the not guilty verdict in George Zimmerman's murder trial. They shouted slogans like "No justice, no peace" and marched toward Times Square, slowing traffic all around the city. Police tried to contain the protesters, but couldn't keep them funneled into controlled lanes. A smaller protest of about 500 people broke out in Boston's Roxbury neighborhood, and around 100 people protested in Oakland, where an American flag was reportedly burned and windows were smashed. Zimmerman shot and killed 17-year-old Trayvon Martin in February 2012 but claimed it was done in self-defense.
