I agree with the comment about ethics or a lack of. There's a difference between hunting and killing. I've also witnessed this several times with calves being orphaned and the grea hunters off with their prize. 
Part of this problem can be attributed to fish and game and their inconsistent rules. You're not allowed to shoot a grizzly with cubs, but you can shoot a cow moose or caribou with a first year calf. 
Giving Ahtna any control over management will be a disaster. Now the argument should be made that all property owners also have the right to manage fish and game on their private property too. So much for equal protection. 
Myself and others who hunt in unit 13, have been threatened and harassed by Ahtna on state lands. This will only get worse now. 
Until fish and game comes up with consistent rules and all individuals have to abide by the same rules, these issues will only escalate as we are becoming a divided nation due to special interests.
