the ID card is news to me, but since the late 80's there has been a movement towards restricting the use of cameras in many 'public' areas. the public areas i refer to are those that have been bought by property developers and who have then built communal shopping areas, relaxation areas, pathways through overlarge corporate environments - for example, i was stopped shooting in the Trocadero since this was private property, and was surrounded by numerous guards even though i had actually got prior permission (this revealed a sort of paranoia, and this was a long time before terrorism was on everybodies lips). Canary Wharf, the Barbican, the area around Liverpool St station, even parts of the river-side South Bank are all off-limits to the photographer without prior permission, even though most people see them as public spaces. This is just as devilish and should be brought to people's attention. Beware!
