Walking through central London as part of the Free Iran protest movement a couple of Sundays ago, I kept noticing the faces of bystanders. There was certainly very little in the way of support. But equally, open hostility wasn’t the predominant response either. Many of the expressions were marked by something harder to discern – a kind of consternation, an ill-disposed bemusement, as though what was in front of them couldn’t quite be metabolised, not without a certain level of discomfort anyway.
