Penn and Teller are not bound by the ethical code psychologists must follow. They are therefore allowed to have a nine-year-old shoot a real rifle with real bullets on TV under the supervision of a weapon specialist. I don't see anything like this getting past a university ethics committee, but I'm sure the mother gave consent. I won't spoil what happened, but this is one powerful way to show that any concerns about young violent video gamers actually gun toting given the opportunity is ill-conceived, and as far as I'm aware this is the first piece of evidence of its kind. Despite its many flaws this mini experiment certainly makes its point.
