Wildlife officers kill bear that claws homeowner

In this article a bear that went into a garage and clawed the homeowner was shot and killed. The Denver Post. My question is why would you kill the bear that went in the garage and clawed the homeowner. Its called a bear of course its going to attack its an animal. We did take over their land so if they can't find food in the territory we left them of course they're gonna go off to find some food for themselves somewhere else they're not just gonna sit there and wait for food to fall into their lap, they need to eat too. Plus when we took over some of their land the bears didn't come out and shoot the people which is what we do. When they come down some are taken back but others are shot and killed so what can a bear do up against a gun. They need to do what ever they can to survive just like anything else and for them to come down means its because most of the time it is necessary. But im not saying dont kill any bears but we should limit ourselves because what we do to them affects us to.
