I was in London yesterday and security is stepping up in the countdown to the Olympics.  The sight of guns on the street still scares me: I'm not sure whether it is the casual way they are held, more like musical instruments, or the size of them or just the principle that they are there.  They make you feel guilty, even if you haven't done anything.

They were stubbornly persistent in the eyes’ corners.  Hi-vis contrasts of black guns against the yellow vests.  She sensed the barrels sniffing fear as she passed.
