There is more to this story than the report shows Im sure. Bears dont just go postal. Food, cubs or some type of idiotic behavior was no doubt involved, (past or present). Im not saying that bears cant be vindictive. The bear may have been POd that the campground was suddenly cleaned up and his easy garbage supply was gone. Perhaps the tent occupants were playing Metallica too loud and the bear couldnt take it anymore. I simply doubt that the tent residents were soundly sleeping, and minding their own business, when a bear came out of nowhere and attacked them.
People have been prey to large predators for as long as there have been people on this continent. Bears, every species of them, are first and foremost predators, omnivores. As we have reintroduced bears and other large predators, and protected them allowing their numbers to expand, so have the number of conflicts between large predators and people.
The responses of most people to incidents such as this one vary widely, as one might expect. From "kill them and let God sort them out" to "It wasn't the bear's fault, those people must have done something wrong to provoke an attack". IMHO, the bear was doing what bears do, where bears normally do it. News flash: Bears are NOT people too. Bears do not have rights other than the limitations placed upon people by the government agencies charged with management of this wildlife resource.
People will be stupid in bear territory, that is a fact. Bears are also capable of being stupid in people territory. Another fact. What people consider normal and reasonable human behavior can and sometimes does lead to conflicts with bears (and othr large predators). What bears consider normal and instinctive behavior sometimes leads to conflicts with people.
Parks and campgrrounds in areas inhabited by bears may not be a good idea. So what is the solution? Remove the bears? Remove the people? Educate both the bears and the people? Accept the depredation on people as normal and continue present policies?
I recently watched several films showing "stupid human tricks" that resulted in attacks by wildlife, Bison in this case. In all of these, people simply failed to realize that the animals were not cartoon charactors, and not jersey cows. In these, the did obviously behave foolishly and provoke the bison, defying established regulations designed to minimize conflicts between park visitors and the animals.
Present policy is to destroy any bear that attacks a human for any reason, their fault, human's fault, or nobody's fault. This policy recognizes the fact that human life has more value than that of a bear.
