Six months after those 1968 riots, I was watching the Olympic Games from Mexico City. An African-American, Tommie Smith, won the men's 200 meters in a then world record time of 19.83 seconds. Australia's Peter Norman finished second, while another African-American, John Carlos, took the bronze. As they ascended the traditional three-level podium to receive their medals, it was apparent that something was different. Smith and Carlos were shoeless in black socks, and Smith wore a black scarf around his neck. Then, as the flags were raised and the playing of The Star-Spangled Banner" began, Smith and Carlos raised black gloved fists into the air, and both men stood with heads bowed until the National Anthem was completed. The image of Smith's right hand and Carlos' left, both outstretched against the night sky, burned into our collective memories.
