Thank you for the video. I'm SO glad Nightline did this. But, it seems to point out this is a random thing. Since 52 of 52 horses at the championships tested for illegal substances, doesn't this point how pretty much everyone winning in the high stakes is doing this? It's sort of like saying you caught the one dog fighter breaking the rules.
I hope this spreads. I'm going to send it to people. I suggest others do the same.
