Why cant brit's do david cam ukraine style :P?

Anyone else saw on tv the egging in the ukraine parliment.....few thousand egg's from protesters thrown at a guy (he had umberella) must of seen it coming lol....I wanna ask what would happen if david cam had got this kind of egging instead of just one egg from a student? Are british people too polite, too reserved or maybe more respective? Everyone cheared the guy who egged cameron but i guess we might all be too chicken and not wanna spend the eve in a police cell lol
