you can make extreme examples, but look at the situation in Mexico a few years ago. There was no video evidence and they were still able to determine, based on the cuber, and the situation, that he definitely cheated. Feliks is not a cuber who needs to cheat to attain world records.
Honestly, I would rather just have ever WR require video (other than FMC). I don't want to stray too far off topic though. I made my case long ago, and more people disagree with me than agree with me, which is fine. If people are happy with the current system, then there's not much more to say.
