2012年 Trayvon Martin 枪击案后，O8有一个发言。抛出了著名的 “good boy” 说法。

President Obama, speaking to reporters on March 23 after federal investigators were deployed to Sanford, said, "When I think about this boy, I think about my own kids, and I think every parent in America should be able to understand why it is absolutely imperative that we investigate every aspect of this.... If I had a son, he would look like Trayvon."
