Been keeping up with some of it through Sue Wallis, Wyoming State Representative, President & CEO of United Organizations of the Horse, and co-founder of the United Horsemen and the International Equine Business Association.
Here is a link to that girly site FB and the group she has organized. It is a closed group and you have to ask for permission to join but there are a lot of articles regarding this and what they are looking at in the future. Of course we have all of the bleeding hearts commenting about it but their comments are so far fetched and stupid in my opinion. Prior to 2006, horses were slaughtered on a daily basis and it was not sold in US grocery stores, most horses that went to slaughter were the older, crippled, or too rank to use. But it gave a place for these unwanted horses to go instead of being turned loose and /or starved to death.
Look up the Facebook group - PRO HORSE SLAUGHTER ADVOCATES
