What to do when two countries can't agree on the rules of a particular event? You go with the home court protocol...even if you get a ton of backlash for it. That's what happened in 1908 in the finals of the men's 400-meter race, when American John Carpenter maneuvered to block Britain's Wyndham Halswelle— legal under American track rules, but illegal in Great Britain. Carpenter was promptly disqualified, because the Olympics were being held in London. Yet the other two qualifiers left with Halswelle were American and were so angered by the ruling against Carpenter that they protested the ruling by also boycotting the final. In the end, Halswelle ran the redo of the final all by himself. (Spoiler: he won.)
