The BBC Radio London website provides a few "JamCam" pictures periodically grabbed from some of London's CCTV cameras used for traffic management.
Usually, these non-real time images, every 5 or 10 minutes, are censored whenever there is any kind of Police "incident", either by no longer updating the image or by displaying a "not available for operational reasons" graphic.,
This rather defeats the whole point of providing informatuion to commuters so that they can plan their journeys to and from work, and avoid traffic jams.
Today's Carol Service in Parliament Square, due to start at 18:00, has not yet been censored and does show a few people gathering in the bottom right of the image, from the Whitehall/Parliament Square camera
.
19:05 the image has changed to the "not available for operational reasons" one.
Does that mean that people are now being arrested ?
