pain in the arse that was for going out raving at the time

The City of London put up checkpoints to prevent terrorism after the Bishopsgate bombing.

<politician's cap> In response to the duty of care that TfL have to ensure that traffic is properly managed. We are already in breach of EU regulations on air quality in a number of sites in Lonon. Without careful consideration of the traffic flow it is impossible to do much in the way of improving the network. <politician>
<disgruntled employee> If you think this is bad so far, you haven't seen anything yet! Checkpoints are nothing compared to what is currently being planned. TfL are proud to present 'Enclosures' <disgruntled employee>
Only the police have the power to pull over a motorist so they have to be there.

Yes. The way they worked it here was to have the officers running the checkpoint directing traffic into lanes to speak to the census taker. You could refuse that, then drive-on, but as you began to leave the checkpoint, there was another set of officers waiting to direct you into another lane where the police/agencies were waiting to administer their own set of checks - Which you could not refuse.
Folk generally put up with it but the 2-tier system did hack-off a lot of people IMO.
Details????
What's ANPR?5. It is extremely unusual for the police to operate their own road check simultaneously with a census point (though if they note any apparent offences whilst processing vehicles for the census - e.g. no tax, dangerous condition, driver appears drunk (and now ANPR indicating the vehicle to be of interest for some reason - they never used to routinely check the police computer for all vehicle numbers but ANPR technology now makes that possible) they will deal with those matters. If there was evidence that officers were ONLY stopping vehicles which failed to coopperate with the census and ONLY doing so on that basis, there would be grounds for complaint.
Automatic number plate recording technology. It's linked to CCTV cameras and automatically reads number plates and instantly checks the database it is linked to (in this case the Police National Computer), sounding an alarm if it has any interest reports (stolen, involved in crime, no tax ...) on it. It can do dozens in the time it used to take for an officer to radio the details to the station and for an operator to carry out a manual check on the computer, read the results and radio back.What's ANPR?
