A few minor pops

There have been a few minor pops in London - one on a bus and on a couple of Tube trains - with no one hurt. Let's hope a sense of proportion is maintained.

In the interests of that, I'm sharing a small piece from this week's Private Eye.

My bet is that this is a pretty amateurish effort to cause panic. The sensible thing is to ensure it doesn't.

I was planning to go to the library but have put it off, just because the traffic is bound to be bedlam all afternoon.
