What i think it might lead to, is perhaps a tightening of the law of being photographed/filmed in public. In the same way the upskirt law came in, when someone got upskirted at a festival. As currently it is a very grey area, with no boundaries for women unless upskirted.
How can they tighten the law? Now that is really difficult.
For example if I photographed a guys face twice on 2 different occasions during street photography, that is technically harrasment. If I followed a nightclub lady for 5 minutes filming every movement then that isn't harrasment.
There are certain countries that have banned all public photography, France and Hungary are 2 if memory serves me right.
The Duran clue I've seen on the C&T Facebook page is Hungry like the wolf in emojis, specific to the Essex events - that's definitely bigger events than Piece Hall and Scarborough - more like Lytham/Cardiff.
They are staggering them across the morning, so probably some different acts in there.
