Quite simple, just post a link or give a description of what you think is the most disgraceful moment in sports.
For me, the death of Roger Williamson in the Dutch GP. His car crashed, flipped and caught fire, fellow driver and friend David Purley stopped his car and got out to try flip the car and get Roger out. While this was happening the track marshalls were on the track kicking parts that fell off the car off the track. Once the fire started to get to big David was pulled away by marshalls and te car was left to burn with Roger still in the car. What made this so much worse was some members of the crowd wanted to help flip the car, but were stopped by marshalls/guards with dogs.
Close second was a Spanish GP (can't remember the date), where the day before the race it was found the track barriers were unsafe. The team wanted to cancel the race and wait for updates to the barriers, but the race organisers threatened to sue the team with breach of contract. This forced the teams to race and during it a car's rear wing broke and the car flew into the crowd killing three people. The race continued for three more laps and the organisers still held a celebration.
