Guy Eastman wrote a good article about this issue. He points out just how much hunters will receive blame for, what most people believe is a reprehensible act. Whoever did this is a criminal but it's more likely than not, in my opinion, a hunter too. That's unfortunate for us all. If I knew who did this, I'd turn him in, in a heartbeat and donate the reward to a good wildlife management program.
I am sometimes surprised at the misdirected hatred that gets spewed out on the wolves. I doubt that the wolves asked to be introduced. They are doing what wolves do, they kill things! They are not evil, they're just wolves. Idiot people dumped them on us and have caused them to propagate to a level never fully anticipated (hopefully). Our effort and money would be better directed towards defeating radical preservationist groups that can't see the wisdom in proper wildlife management, which includes predator management. Going on public forums and stating that we should kill all the wolves certainly is not going to further our cause towards the better, it just put us on a par with the other side of the issue.
Learn about sound management strategies for wildlife. It more complicated than you might believe. The more you know, the more intelligent you can argue our points about predator/prey management and interaction. Learn all you can about wolves and their interaction with other species and the environment.
The wolves are here. We'd best get used to it because we'll never eradicate them. I'm not a "wolf lover", I have shot several of them. However, I would never shoot one illegally or do something as dumb as what happened in Idaho.
My thoughts; get involved, attend meetings that address wildlife management, make your voices heard in a positive manner, especially to legislators and decision makers. Donate money to good organizations like RMEF, etc. We can make changes without resorting to civil disobedience or writing caustic blogs on public forums.
