All we know is, he didn't have a valid ticket, refused to buy a new one, refused to leave the train which held the train up, he was then removed from the train. Why should he get away without having a ticket and get to where he needs to for free?!
Calling this assault is absolutely pathetic, the idiot tried to get back on the train and was shoved off, his decision, advocating him not being a 'typical' hoody further undermines any argument, one rule for middleclass in education and one for the poor? (difference being someone that chose to not pay the fair vs someone that might not have been able to, who's more guilty?!)
When will people take responsibility for when they are in the wrong?! Pay for ticket, don't get chucked off, simples!
