Cincinnati Zoo officials had to shoot and kill a 17 year-old gorilla after the gorilla grabbed and dragged a four year-old boy who had fallen into the gorilla's environment. The boy was with the gorilla for about 10 minutes before zoo officials put the gorilla down. Video showing the boy in the presence of the gorilla is below.
I suppose the only question now is how long before we have to endure the PETA protests? After all, under their perverse worldview, what difference is there between a gorilla and a boy?
