ESPN has a video (here) of a bull that charged into the stands during a bull fight and injured about 40 spectators. Although I'm sorry about their injuries, I'm glad the bull turned the tables and exposed the spectators to a substantial risk in what is, normally, a stacked game. Bullfighting is a cruel sport, which should have no place in the modern world. It wouldn't be so despicable if the risks were more fairly distributed between the bull and blood-lusting spectators (a la the running of the bulls at Pamplona).
Now, if we can only figure out a way to weaponize game animals hunted purely for sport (I have no quarrel with those who hunt for meat or as an occupation to support their families).
