Mate, some guy was a split second from pulling him off the train, he had to do something.
Good. They shouldn't have been up there. They have absolutely no right to do this.
Their stupid tactics are causing nothing but costing money and police time and, in this case, derailing people who have nothing to answer for trying to get to work.
It won't further the worthy cause. And of course, it is a worthy, albeit stupid in cases like screaming it's the end of the world like lunatics, cause. We have to do something.
But this is not it. Their protests are now criminal in some cases.
Today's example was just endangering themselves and others. They haven't raised awareness of any issue. They've just proved how ridiculous and self-righteous they are.
Now I do not condone in any sense the actions of the people at the station laying in kicks and punches. But I think if I was there and needing to get to work to earn a living, then I'd be grabbing the pleb off the train too.
