got to say I am 50/50 on this story :s
Reason being, I used to work in a large shopping centre in Romford in Centre mgt security - during my time there, we had notificaiton of a royal visit... the queen was coming to Romford (god knows why !) lol. So, a blanket ban on photos being taken in and around the centre was put in place at the request of royal protection..... on one side, pretty stupid as if someone wanted info they would do it covertly lol. But had to be enforced all the same
As it was private property, we could ask people not to take photos and if they insisted they would be asked to leave, then removed by reasonable force if they would not.
In this case though, seems overly daft being he was taking a photo of his kid... enjoying herself !
