The best and only way to ensure fair, equal and meaningful competition among athletes is to enforce all rules as objectively as possible.
This must apply at any level of competitive sport, from Special Olympic, Paralympic through Olympic competitions.
It's unfair and problematic when rules are subjectively bent or ignored (out of sympathy or other reasons). Unequal application of the rules of competition compromises the respect and dignity any and all athletes deserve.
Athletes (and people) need to be treated like athletes (and people), and that applies to athletes and people with disabilities also.
Not applying or enforcing rules of competition due to a perceived lack of competitive advantage gained would add an additional level of subjective rule interpretation by officials/referees trying to determine the relative amount of any potential competitve advantage gained.
A world class NFL football player would have his last second breakaway touchdown run disallowed if they did not cross the goal line in possession of the ball because they were avoiding an injured teammate, and their team would lose the game.
A world class MLB baseball player would have their walk off 2 run home run disallowed if they did not touch home plate to avoid their teammate/baserunner who had fallen over after crossing the plate, and their team would lose the game.
A world class Paralympic marathon runner with a large lead on fourth place would have their finish disallowed if they lost connection with their guide runner before they crossed the finish line because their guide/teammate was near collapse, and their team did not win a bronze medal.
None of the above examples should be treated differently. You can feel sorry for and sympathize with the individuals and teams involved. The media will give these incidents attention. But it would be unfair to not equally apply the rules of competitive sport in these or other situations.
