Oxford Street is Closed

I'm such a fool.
Back in about 1992, a kid (non-white, non-asian, non-oriental) got on a train at Westbourne Park, stood by the door, glaring at everyone one the train. He then pulls up his t-shirt and shows evryone that he's got a gun stashed into his belt line. He was no more than about 15 or 16. I thought "loony kid, probably got his dad's gun - anyway, that'll never happen again".
Had I known how wrong I was, maybe I'd be in Japan now.

Que??
