For a second time this year, circus lions have been shot by police in a Brazilian town. In the latest incident, six lions escaped from their cages, attacking a horse and threatening the safety of people in a town in southeastern Brazil. The lions were gunned down in the streets by local police. Both cases stress the inherent danger of wild animals in performance.
Wild animals are unpredictable and dangerous at all times.
No amount of training or handling will alter this fact. As long as elephants, bears, big cats, and other wild animals are on the road in performance, more incidents like these will occur.
