Hey, I believe there are many rigged races. Google Esmeal Jaramillo or whatever his name is and there is a YouTube video of him putting a buzzer in his mouth after a race. However, there is no way he would intentionally drop off a horse and get stomped on, which he did, to fix a race. He would have remained buried and came in third if he wasn't supposed to win. The guy easily could have died. Yes, he is in the 'know who to win' group, but to dive off a horse in front of 10 other horses is suicide. He lost a stirrup and went down.
