I might well have misunderstood your comment about the Guardian twitter article, but if you note its publication date then you can see that it is a rather poor joke. Apologies if I've completely misunderstood your point. It is definitely absurd. Perhaps that was your point.
I went to the Stasi museum a few years ago. I was reminded of it when Gordon Brown suggested putting listening devices into lamp-posts to listen for terrorist activity at the 2012 Olympics. Does anyone know if this is still going ahead?
