was just zipping around the back of Oxford Street to day doing some Christmas shopping on the motorbike and come round the corner by the US embassy and get pulled over by diplomatic police checkpoint of sorts under the terrorism legislation. PC very polite and apologised for delaying me, explained what it was all for and took details from my license. i asked if they had ANPR but apparently broken today , he said they do 45 minute stints by the embassies, in Whitehall or by MI 5 (?) building south of the river. he gave me a slip of paper to say that i had been stopped, i told him i wouldn't be writing to my MP in a civil rights fury. he bade me goodnight sir. two reactions 1) doesn't strike me as a particularly effective anti terrorism weapon but maybe its to catch all those people on fake plates that slip past the ANPR every day and 2) the first thought as an armed policeman steps into the road with palm facing me is not "who me?" or "this is for jumping the light in Wigmore Street" or "is the MOT up to date?" but "great, this is going to be a good thread on MBClub".
