Like many other Olympic athletes in the past, Ethiopian marathoner Feyisa Lilesa made a gesture Sunday night when he crossed the finish line in Rio.
But simply making the sign with his arms could have cost the silver medalist his freedom or even his life if he returns home.
He told reporters after the race: "I was protesting for my people. ... If I go back to Ethiopia, maybe they will kill me. If I am not killed, maybe they will put me in prison."
