If the numbers are too high, it's only in relation to a prey population that is in decline due to factors other than that represented by their natural predator. Where is the proof that predation is the cause of the decline? The fact that adults currently constitute a larger than normal percentage of wolf kills is not proof that predation was the cause of the decline. In fact, it's more likely to be evidence that the populations age distribution structure is seriously skewed due to the pre-existing decline.
Now, having said that, if people want to hunt wolves legally, that's one thing, but "knocking them back" or "culling" are just euphemisms for slaughter, government run slaughter in the case of the latter term. I'm not a fan of predator culls because they don't solve the problem; they are band aids to a sucking chest wound. However, for us as a species, it is easier to shift the blame and have another species pay the price, rather than look for the real solution and how we contributed to or created the problem in the first place.
