Rancher tries to do the right thing and gets his face knocked in the dirt for his trouble. Don't forget to smile, say thanks, and ask, "May I have another". A damn sorry situation.
Shy of spending $150,000 to hire a PHD and his assistant to come out and do an "official" and "scientific" study of your wolf situation and what you "think you saw happen"

, I doubt they will listen to you. I empathize with your situation.
I would be very careful of openly stating your intentions regarding future handlings of this matter. The federal government has deep pockets and too many folks with lots of time on their hands and can easily get to the name behind your internet account by supoena if a wolf kill is discovered in your area. They'd like nothing better than to make an example of you just for publicity purposes. By the time they get your report written up, it won't matter whether you did anything wrong or were justified in your actions from a common man's perspective, it just won't read that way.
Good luck with a very crappy situation,
