I was looking at the start of a demo in Parliament square on 14 March. I was hoping to save pics every minute or so for a 'time lapse' video film of the action.

Shortly after the start of the demo the camera went offline, and only came back on at the end of the demo.

I contacted the BBC and they advised me that, to thier annoyance, the Police often did this. Their reason? To avoid allowng the public to see incidents that may not be 'especially pleasent'. Perhaps that should read 'especially pleasent for the police'.

Presumably the police fear that the evil rapscallions on the demo may use the camera images for their own evil ends, ummm, like showing what happened. Bizzare.
