Have you watched the video carefully?
1) Prior to the race Liquori and whoever he's commentating with lament how even though it's been a great year for here the time "won't count" because of the wind. Do you think that the commentary team conspired to screw Flo-Jo out of an impending WR they never knew was going to happen by claiming it would be wind aided when it wasn't?
2) At the start of the race the numbers on the back of the women were almost blowing off because of the strength of the wind from behind. At the end of the race the hair of Griffith-Joyner is blowing up off her head as she walks back towards the start finish line indicating the wind is coming straight down the home straight.
3) To debunk this frankly idiotic "It was a crosswind then nothing then a crosswind" concept you have, this didn't seem to be the case in the 3rd womens QF where the wind was +5.0 for Gwen Torrence (in QF2 the wind was also 0.0 which is also evidence for some kind of faulty gauge but more likely one not even turned on because getting two perfect 0.0's on a day with any type of wind is almost completely impossible) and also for Carl Lewis in the mens 100m final (run at 4.35pm just after the womens QF) which was +5.2. Even more telling is the wind gauge for the mens triple jump was hitting 5's and within seconds of this performancer of FGJ, Willie Banks jumped 18m20 with a +5.2 with a wind gauge sitting right in the center of the triple jump runway literally feet away from the 100m gauge.
I wrote this a while ago, I just can't even comprehend why, even if you want to say Griffith-Joyner was clean, that any track and field fan can't just concede that a mistake was made that day in Indianapolis (either a gauge that didn't work or wasn't turned on) and an even bigger one made ratifying a record that shouldn't have been. I don't understand any benefit for and in trying to do mental gymnastics to try and convince oneself this just wasn't legitimate other than being borderline insane.
