It amazes me how some people can twist info that they go. I really wish this guy would go to jail or get in some sort of trouble, but I doubt that'll happen. There was another story where a man, I believe drug a horse to death and he either walked or got a slap on the wrist. I'll have to find the article to get my facts straight, but it just disgusts me what some people do, whether it be out of ignorance, or stupidity or whatever you want to call it.
I am very glad to hear that your brother is taking care of Gray. I will keep Gray in my thoughts and I wish him a healthy recovery.
ETA: here's the article. It was a worse situation than what Gray was/is in. http://www.aldf.org/article.php?id=921
