Man Shoots Moose. Justified? [VIDEO-POLL]

I saw this video of a man who was out snowmobiling and ran across a moose in the trail.

Here is his description of the encounter.

A man, age 51 with a life threatening heart condition (dilated cardiomyopathy), while snowmobiling out west with his son, comes upon a moose in the wild. Concerned that an animal attack might be about to happen, the site seeing experience goes bad when the moose, not wanting to be on camera, decides to charge. Coming over the snowmobile, the 1,000 pound bull attacks, kicking the Dad in the chest; the moose's intentions were clear. This was one angry animal attack. With only a hand gun to defend himself and his son, the Father fires a warning shot only to quickly fire 4 more to defer a 2nd attack...when animals attack.

I personally don't think the moose cared about the camera, the heart condition or was clear in its intentions. It is nature and it was acting accordingly. I am curious as to your thoughts.

Please take the poll.
