Though he's the United States' first African American president, Obama hasn't talked a lot about race. Then George Zimmerman was found not guilty in the shooting death of unarmed black teenager Trayvon Martin. A few days later, Obama gave a surprise speech in the White House briefing room on being black in America. "Trayvon Martin could have been me 35 years ago," he said, recalling how he'd been followed in department stores and often heard car door locks click as he walked by. A powerful statement from the president.
