Staged or not (and it's obviously been edited down from many hours of gaming) I'm sure that sort of behaviour is actually fairly typical of socially underdeveloped kids. It's the same kids who react violently in frustration when they're picked on at school. That was me in my mid-teens. He's really not a danger to anyone and hopefully soon enough he'll realise what a {bleep} he looks when he acts out like that... As I did. :-D
