There were efforts to rescue the horses that were already taken there but weren't taken into slaughter, but it was refused. http://www.habitatforhorses.org/whatsnew/effortsrefused.html
We still need to work on getting the Horse Protection Act S.311.IS and H.R.503.IH through the Senate and House, as this action does nothing to keep the horses from being taken to Canada or Mexico for slaughter. Also H.R.249.IH has been introduced to the House to restore protection for Wild Horses.
