Walking up the stairs at Wynyard station this morning, I had to twist my body to avoid hitting an alighting passenger from a train that had just arrived. He was coming down the stairs very quickly. I briefly look down at the stairs from the platform and see that the guy that nearly ran into me is standing on the first landing down, waiting amongst the hundreds of people walking down. Next thing, he grabs a guy and very forcefully tries to throw him down the stairs... The other guy staggers and manages to steady himself on the railing. The first guy then puts his hands around the guy's throat and starts moving down. They ended up letting each other go, it was all over in about 10 seconds or so... I don't know if anything happened afterward. The other thing, they were both well dressed, fully grown men on their way to an office job somewhere. My point is, whatever it was he thought the other guy did... Surely trying to severely maim or possibly kill is an over reaction. But this kind of thing seems to be something we see more and more.
