Wolves are documented as having attacked humans in Europe quite frequently. There is a claim that wolves have never attacked humans in North America. This could be attributed to the fact that Indians didn't keep written records and that the white men that first came west didn't either.
Do you really think that a predator the size of a wolf won't attack humans? coyotes are wolves, just a smaller version and they have been known to attack humans especially children. This is well documented and if you want to do a bit of research on it feel free.
Dogs, a close relative of the wolf and coyote attack humans daily, so what makes you think the wolf won't? Are they some how endowed with a special sense that allows them to determine that humans are not attackable, do they have a "Oh, well they are human I can't attack them!" attitude?
Anyone that thinks wolfs won't attack humans, especially children when they get hungry enough simply have been brain washed by the Bambi syndrome.
BTW if it was your dog you might not be so flippant about it being eaten. Also, you might want to ask the ranchers in Wyoming about all the cattle the wonderful Yellowstone wolves kill every year and mouth off to them about how it is only a few freaking cows and what's the big deal? I am sure they will tell you why it is a big deal.
