We run bison in Wyoming and would NEVER imagine having them around people because they’ll run you down and kill you just for looking at them! Shooting them was the right thing to do if they were loose in a town. No doubt about it!
While I’m not against that based on the comments about the Bison being very hostile to humans, in a city the shot is very dangerous because of the possible humans behind the animal even blocks away.
If the animal kills someone it’s obviously bad because they could have been shot.
If someone is shot mistakenly, it’s bad because the shot should never have been fired.
