That question is fine, but it wasn't the one she was asked. Again, here is Gault’s exact question:
“There is one person in history who has run faster than you tonight. I’m wondering what you make of the current WR, do you believe in that time?”
So, the first part of the question is a clear reference to Flo Jo and the second part asks if Flo Jo’s record is legitimate. Not surprisingly, Jackson declined to answer. If Gault had simply asked Jackson if she thought she had a chance to break the WR we would not have 10 pages of commentary about it here.
Also, regarding your analogy with the 4-minute mile (or a sub-2 marathon), I think there are important differences. While the sub-4 was viewed as a barrier to what was humanly possible, it was not associated with any particular athlete. The women’s sprint records are associated with one athlete only. The Chinese women’s distance records are also highly suspicious, but they are held by obscure faceless runners who very few people can even name. Flo Jo was as big as celebrity as we have had in the track world. She was certainly one of the most famous female athletes in the world in 1988, and she also happens to be dead. And I think that makes current sprinters less willing pass judgement on the record itself.
Flo Jo’s records will be broken, and there is a good chance that will happen in the next few years, and then we will have a new controversy to occupy this board, assuming it’s still around.
