It was a horrible thing that happened and it was by no means the MTB’s fault. He was just in the wrong place at the wrong time.
It was a wild animal, doing wild animal things, in the wild. As a person who does outdoor, off the beaten path, in the country sports there is a certain amount of risks involved, both from the sport and the environment that we have to accept! Swim in the ocean you worry about sharks, camp/hike/bike in the back country worry about bears and other large predators, go to arctic area’s worry about polar bears. I just don’t see the reason to kill a wild animal in it’s environment for doing what it natural does to survive. We are in their domain and need to realize that.
On the other hand if sharks, bears, mountain lions, etc start attacking people in malls or coffee shops I might change my mind!
Just my two cents…
