Surprise effects of wolves in Yellowstone

I was not a fan of the "reintroduction" of wolves to Yellowstone when it was done and now that they are way beyond the target population, they are migrating to places that the Feds told them not to go to, like 150 miles south to Lander when they have been killing pets right outside the houses near the town and also livestock close to town. I do believe this foolishness would be reined in if they were to "reintroduce" wolves back into Manhattan, where they also roamed many years ago as well as putting them in DC on the mall and tell them to stay there and not wander around scaring people in the City. I thought it was bad idea then and still think it's a bad idea.
