just seen a couple of 5-series BMWs with blues-and-twos going, forcing their way through the traffic. So far so normal. However, almost all police cars around here identify themselves as either "Metropolitan Police" or "City of London Police" in their stickers. These just said "police". Odder still, normally underneath the stickers, cars around here are white or silver (increasingly the latter). These were painted flouro orange (i.e. the whole car) and I mean "international signal orange" type orange, not some BMW standard paint job. And strangest still, on the back they had two "hazmat" type stickers - one a "skull and crossbones" and the other was the "two spilling test-tubes" thing that means "corrosive material". Oh, and the blokes in the car all had on flack jackets and CIA-style earphones. Any idea?
