A few months later, at the 1968 Summer Olympics, Hines — a black athlete — found himself in a tense situation, with racial riots going on in his home country and a threat of a boycott by the black athletes of the US team, who were disturbed by the controversial idea of admitting apartheidSouth Africa to the Games and revelations linking the head of the International Olympic Committee, Avery Brundage, to a racist and anti-semitic country club. Hines reached the 100 m final, and won it with the time 9.89 appearing at the screen, later corrected to 9.95. There was some controversy over how to his (slower appearing) electronic time of 9.95 should compare to the hand timed 9.9 "record" races of the day. It took until 1977 before fully automatic timing was required of world records. As the fastest electronic time to that point, Hines' mark was recognized exclusively as a new world record. The race was also significant for being the first all-black final in Olympic history. Hines helped break another World Record, when he and his teammates sprinted to the 4 x 100 m relaygold at the same Games.
