So RS purchased a known commodity, got a shipping cert and was waiting on the shipper. Then all hell broke loose, stallion fight, seizure, etc.
As for the lawyer, my guess is it was easier to simply use a lawyer that was already intimately involved with the case. But yes, from a public perception standpoint, she would probably be better served finding a different lawyer. As for suing, I don't know, if I purchased a horse that was subsequently seized, treated without my consent, kept in a clinic for weeks and weeks and I was then informed that the horse wasn't going to be returned to me as he was evidence as well as some other things, I might be inclined to sue as well. YMMV.
I have no personal interest in this case although I have met RS in person. I simply hate to see any person or business dragged through the mud based on nothing more than nasty speculation and perhaps personal agendas. It really is quite depressing.
As for the charity, as I posted, a simple way to stop that line of muck-throwing is simply to post an accounting of where the monies are being spent. Voila - problem solved. I hope it does that, certainly no other witch hunt is needed.
