Since 2014, I've filmed Council meetings and interactions with the Council, despite their protestations that I needed their "consent to film". This paid off when in 2015, the Council relented and officially permitted the filming of Council meetings, and they also recognised the right to film in Public places, of which Council buildings are.
It is therefore frustrating, when PCSO's tell members of the Public, that they cannot film. Not because of any particular law, but because there is a sign say 'filming is prohibited'
This is what happened when we point out that the sign has no validity in law.
