I completely agree. Through my work I’ve also done a pile of urinalysis tests and when they “can’t pee” or just straight up refuse it’s because they have something real bad in their system that they don’t want to be shown in the results. I shook my head when I read the reports on Leonard and listened to Dickenson and the fans defend him.
He withheld the sample because he knows what’s in his system. It’s obviously something that would have ruined him far worse than just claiming he couldn’t pee. The end result is the same as far as punishment but his secret stays safe.
