They should be shot on site when seen outside of yellowstone.
And that is
EXACTLY why the wolf situation is what it is today.
That attitude got you into this mess and it will make sure that you never get out of it.
The wolf problem exists today because people shot as many as they could on site every chance they got. Then came along the tree huggers to protect them and reintroduce them but they are just as short sighted as the people that nearly eradicated them years ago because they had absolutely no plan to deal with the wolf as their populations grew and expanded into new terrotories. Now the wolf is a real problem and, in most states, you can't kill any of them with out risking jail time and thousands in fines.
The wolf population must be controlled and not let go unchecked, as it has been thus far, but the attitude of "kill em all" or "protect them at all costs" does nothing to help maintain a healthy natural balance, establish hunting seasons, etc... etc...
