I don't really know much about the topic, but with the help of google I did find some interesting stuff:
Handling wolf encounters:
Info on wolf attacks:
A documentary on Northwest Wolves:
I can't say I have any strong opinions on this one way or the other, just seems that so far this thread is full of fear and conjecture.
Before quoting or citing any information on any subject it is good to research who is offering the information. There may be a bias based denial in such articles. Two of the articles clearly are by pro-wolf representatives. One of the articles actually says there are no documented incidents of wolf attacks where someone died in North America, yet another of your articles says there are documented cases. Don't you think it interesting that the wolf was exterminated in many parts of North America. I am not afraid of going into the woods but would start carrying a gun if I knew there were wolf packs in the area. Fear and conjecture? read all of the articles you cited and research why ranchers long ago decimated the wolf population.
This reminds me of dog owners who's dogs snarl, show their teeth and lunge at strangers, they are quick to say don't worry he would never bite anyone. When they finally do bite the owners deny and make excuses rarely taking responsibility for whats happened. One of the articles says that wolf attacks are limited to an individual wolf or pack and are not normal for wolves in general. I don't think that is much comfort to the persons or livestock who are attacked by this rare wolf or pack that was reintroduced into an area. If they never were introduced the incident would never have happened.
