Well, as I went to my place of work today certain civic buildings were coned off so you can't pick up or drop off outside them. Vehicles can pass by down the road as normal, but the bit next to the pavement outside the building is cordoned off.
With the terrorist burning jeep hopeless nonsense that did nothing other than singe the occupants and annoy the airport authorites, I guessed this was related. So I asked the nearby plod "Why is this coned off?"

But of course. I should have known that if you are hurtling at high speed towards the entrance of a large civic building in a 4x4 packed with half a ton of explosives, that a row of 18 inch high yellow cones with "Police" written on them will stop the impact.
Why do they bother? Or do they think terrorists are real sticklers for Highway regulations and will think "Well, I was going to park my car outside the council house there and detonate it, but if I were to stop I would be breaching the local parking by-laws and that's n ot what I'm about. No, sir. I'm a law-abiding suicidal maniac intent on murdering dozens of innocent civilians".
Or (and stop me if I'm being cynical here) perhaps it's the government yet again trying to con us into thinking they are doing something useful about the problem by doing something noticeable yet useless.
How about a sensible look at our foreign policy and why it is we keep pissing off half the Muslim population of the world, rather than the sticking-plaster-on-a-severed-limb approach we currently have.
