What's worse mamy in my opinion is people seemed to support the headbutt.
Imagine, leaning on some chairs in a heavily packed train for it to lead to numerous men confronting you, holding you up against the door. You'd feel threatened, you'd feel unfairly treated. To then get headbutted like he did whilst having about 15 cameras pointed in his face, to be met by some people laughing at that action? Heinous and anyone who supports it is utterly wicked.
