At least they werent made out to be loveable pets..... I have never encountered a wolf and believe you either know its coming because the pack is howling and you are surrounded or its quiet and you dont know its coming until they are closer than 50yds.
A trained police office needs 21' at minimum to draw and fire 1 shot at a guy with a knife who is charing the officer before the officer is phycially struck. A wolf covers more ground than a person and faster. Any wolf within 50yds is a dead wolf.
Just like a dead intruder tells no tales so a dead wolf is better than a live one.
