I don't quite know what you are talking about here but I'm going to assume they re-ran the episode from monday night?
what happens to horses after they leave the track is very real, and all the people who supported slaughter bans in the US without closing our borders to those who want to ship to mexico and canada need to see exactly what has happened.
it's sickening, but we have too many horses. Thoroughbreds are not the bulk of the problem, but they are the lightning rod.
this is what they do in puerto rico.....also not the greatest idea, but at least it's cheap, humane, and they aren't letting them starve to death somewhere in the country. Euthanasia has to be an option just like it is for dogs and cats...until breeders (of all breeds) control population numbers.
