"...After the race, the top finishers are tested for a myriad of banned substances and the results for all were clean.”
Statement from Churchill Downs regarding Justify and 2018 Kentucky Derby
The allegation isn’t that the horse tested positive after the Kentucky Derby. The allegation is that the horse tested positive a few weeks before the Derby when it qualified by winning another race. The implication is that it should’ve been ruled ineligible for the Derby.
You’re arguing something that doesn’t matter. It doesn’t matter that he passed the test after winning the Derby, because that’s not what’s being alleged.
