About 3 months ago, I was cycling home from work, when I stopped at some lights. All of a sudden this blue armoured police vehicle screamed past, sirens blaring. There happened to be a copper standing at the lights themselves, and I asked him what it was. He said "In 30 years in the force, I've never seen one of those".
Last week, again cycling, but this time going to work, I stopped at some lights not far from the original ones and a stream of 6 or 7 of them trundled past in convoy:
Without wanting to sound like a big tart, it was quite sinister seeing them nonchalantly cruising along in unison.
Added to the recent acquisition by the Met (with Boris Johnson's go ahead) of a million quid water cannon truck, things are starting to look a bit grim round these here parts.
