I found this to be a touching story that I didn't know anything about. I actually wondered how the third guy (Australian Peter Norman) felt about the Black Power salute. I had assumed that he didn't know ahead of time about it. This is much better. Shame he hasn't gotten more recognition.

An apprentice butcher from Melbourne, he had learned to run in a pair of borrowed spikes. More significantly, he had grown up in a Salvation Army family, with a set of simple but strong values instilled from an early age. As his nephew Matt Norman, director of the new film, Salute, remembers: "The whole Norman family were brought up in the Salvos, so we knew we had to look after our fellow man, but that was about it."
In Mexico, that was enough for Norman, who felt compelled to join forces with his fellow athletes in their stand against racial inequality.
The three were waiting for the victory ceremony when Norman discovered what was about to happen. It was Norman who, when John Carlos found he'd forgotten his black gloves, suggested the two runners shared Smith's pair, wearing one each on the podium. And when, to the crowd's astonishment, they flung their fists in the air, the Australian joined the protest in his own way, wearing a badge from the Olympic Project for Human Rights that they had given him.
