If horse slaughter could be made more humane and less gruesome, would anyone here support it?

This question is a repost, and is being asked as part of some personal research I am doing for a book that I am writing. Before I post this again, I am going to add a few disclaimers. 1. I am NOT sick because I support the idea of slaughter, provided that it is made more humane. 2. I do NOT and DID NOT get my information from PETA, HSUS, or any other animal rights group. I view most of those groups as little better than eco-TERRORIST organizations, in fact, because they prey on peoples' fears and ignorance and don't give legitimate pet and animal owners the right to speak for themselves. 3. I am WELL AWARE that the captive bolt guns which are currently used to destroy animals before slaughter DON'T always work reliably. Bolt guns are OLD, antiquated technology which should have been replaced decades ago, if you ask me. My proposed idea, as part of the process of making slaughter more humane and less gruesome and cruel, would be to replace the bolt guns with something like a more powerful version of a Taser stun gun, or perhaps to have the animals enter a carbon dioxide chamber and become unconscious prior to being destroyed. One of the reasons I am asking this question is in part to see if there is anyone here who would agree that this might be a better way to destroy animals while still preserving the safety of the meat. 5. Another part of my proposal would be to ensure that animals destined for slaughter are cared for and given food and water, and are transported in something OTHER than a cattle truck. Certain categories of horses would automatically be exempt from slaughter, including very young foals, mares with foals at foot, pregnant mares and so forth. 6.Last, before anybody answers this question, PLEASE READ IT ALL THE WAY THROUGH, and remember that I am doing this for research purposes. I am NOT doing it to make people mad. If you are strongly against slaughter of any animal ( regardless of what animal it is) don't answer. Likewise, those of you who are PETA members need to ignore this question. Please watch your language and mind your manners when you answer, because I can't use profanity in the book I am writing. Thank you.
