What any coach will tell you and keep repeating is: "Keep your eye on the ball!"
The same applies here.
All that is distracting from the real issue, the drive by animal rights extremists to eliminate all uses of animals, one at the time, here handily because they have some abuses and, since horse slaughter is the most regulated of them, well, many inspector reports and all that they can use for their propaganda, etc.
The goal here in these drives to ban?
Distracting you from seeing the ball for all the hand waving, that here is just that, regulations and inspections and how the process works and what can be made better where it doesn't.
I will insist, horse slaughter is just a process, as good as the ones managing it and as such, definitively not perfect, but also not "all abuse!", as some may want you to think.
Why work on banning a perfectly good way to get one more use from SOME horses after they are dead?
Those same horses will then be killed in euthanizing clinics and wasted and that is more objectionable than at least, thru slaughter, make their lives and death mean something more than discarded as trash in a landfill.
We are not talking about your horse or mine or the next one standing there, but those the horse industry is not using any more for any other, thus the euthanizing clinics or animal control killing them, if we don't have slaughter.
Now, back on the topic of this horse, that seems to be a horse that some wanted, had a different use than dead and he fell thru the cracks, which he would have done if there was slaughter or not, as it seems several of his owners were quick to dump him when convenient.
That this happened to this horse and happened thru slaughter, that, again, is no reason to want to ban slaughter, but to tighten the requirements so that doesn't happen, as with others in such situations, with someone wanting them, as I know happen in the Dallas plant, they were held back until their situation was resolved, the owner sorted out.
That is assuming the story as told is the whole story, there is not more to explain why things ended like they did.
Par for the course, one horse was killed because someone didn't wait to resolve what the situation was, against others where, even when questionable, the horses were held to clarify the situation, as they should.
Make regulations better, so horses like the first one are not killed, don't take that situation out of context to brand all slaughter as evil and ban it because, see, some times mismanagement happens.
Where does that make any sense, but in the eyes of animal rights extremists, that see any such story as a good way to eventually eliminate all uses of animals, one at the time, as their current president said several times over several years: "One generation and no more domestic animals and none too soon for me".
