People insisting that the tiger should have been shot to save this guy are operating from the same riak-elimination mindset that has led to "don't exit bus until it stops moving" signs. From all accounts it was extraordinarily difficult to get into the tiger cage. You couldn't just accidentally fall in, or hop over a waist-high railing. The guy had to scale a tall fence, and apparently did so after fighting off people who tried to stop him. So then people will say oh, the fence should have been taller, or it should have been topped with concertina wire, or it should have been entirely enclosed. Fine, you do that, and then someone even more suicidally determined comes along and finds a way through r additional expensive security measures. They bring wire cutters or something. So then that doesn't work, and people say ok, well zoos just shouldn't have tigers then, they're too dangerous, retards might get hurt, we need to cull the tigers to save the retards. So then no one gets to enjoy tigers and tigers go extinct. Designing our entire society around the tail risks created by the most retarded people in society is, in fact, retarded. The purpose of society should not be insulating the stupidest among us from the consequences of their idiocy.
