Much has been written about President Obama's impromptu remarks about the Trayvon Martin case in Florida and, more broadly, race in America, on Friday.

Amid this sea of words, it's worth re-watching or, for many people, watching the 18 minute (or so) speech by Obama. As we tweeted at the time, Obama's remarks were among the most personal and, therefore, the most insightful of his presidency. It's well worth checking out.
