You may remember this photo from last year. Much has happened since then...
Last summer, Patrick Hutchinson was caught on video rescuing a man at a London protest that had turned violent, and unwittingly stepped onto the world stage.
He and some friends had turned up to observe the protests, where racial justice demonstrators and far-right counter-demonstrators were clashing, and Hutchinson ended up carrying an injured white man to safety. His good deed earned him praise from Prince Harry and the Rev. Al Sharpton, as well as appearances in Vogue magazine and on the cover of Men's Health.
It wasn't something Hutchinson, now 50, had planned - but he's turning his fame into a path for change. Hutchinson has written and published a book called "Everyone Versus Racism: A Letter To My Children," and recently, he and three of the men who were with him last June - Jamaine Facey, Chris Otokito and Lee Russell - started a group called UTCAI, which stands for United to Change and Inspire.
"Go out there and do what's right," he says. "Don't stand by and watch certain things unfold when you know that you have the ability to do something about it."
