The shooter and the location of the shooting are nowhere identified on the Web. A lot of viewers are indignant and express criticism that the snowmobiler did not turn around or leave the trail, but snowmobiles have no reverse and it is really unlikely that he could have gotten his machine out of that tree-bordered trail. The YouTube version offers additionally the extenuating information that the shooter had a heart condition and was defending his son. Obviously the moose could have left the trail more easily and the moose clearly initiated a physical contest for possession of the right of way.
73% of respondents to a Wyoming radio station poll thought the shooter should have done more to avoid the confrontation. I do wonder how many would have felt the same way when on the receiving end of an incoming moose hoof.
I was myself surprised to see a Glock so effectively drop a moose. I wonder what it was chambered in.
