Amidst the aftermath of yesterday's attacks on London, there's a combination of "now's not the time" and "let's talk about security".
Many things are being bandied about in the media, such as full-body scanners on the tube, and "some unnamed technology" that QinetiQ are puting in. There's also talk about police searches of "suspicious" people on the tube.
None of these address the problem, which is remarkably simple, yet no one seems to want to mention it: stop being duplicitous, particularly abroad, and terrorism stops.
Terrorism, it seems to me, is a bit like germs in dirt. Wherever there's dirt, germs live. Where ever there's dishonesty, terrorists live.
