War On Errorism

I was at the Science Museum shop the other day (yes, the shop is more fun than the museum itself), and as part of the merch for their Spy exhibit they have a pin/badge/button saying 'Self Destruct'.

Luckily this is in London, not Boston - otherwise wearing one could get you blown up. As Bruce Schneier put it: 'Boston PD - Putting the "error" in "terror".'
