People take pictures of a damaged BART police vehicle vandalized during a protest July 14 after George Zimmerman was found not guilty in the 2012 shooting death of teenager Trayvon Martin, in Oakland, Calif. In the week after the verdict, amid peaceful protests involving tens of thousands of people across the country, there was some violence_ but community leaders and scholars say the overwhelmingly peaceful response to the Zimmerman verdict reflects increased opportunities for African-Americans, the powerful image of a black president voicing frustration with the verdict, and the modern ability to create change through activism and social media rather than a brick.
