If you see one with an expression like that on his face…
Don’t run or turn your back on him.
Stand as tall as you can, and back away slowly.
If I ran into this critter… I’d have my rifle on it as I backed away slowly… and if it moved I’d blast it. I am not afraid of bears, I respect them and most of the time they will reciprocate.
But these evil buggers? They will usually run away but enough of them won’t… they will start hunting you. Or worse - the kids. They will torture their prey too. I won’t fear them, but I will take them seriously.
