There is definitely an anti-photography mentality about in this country; is it that we've become a very nervy, aggressive bunch? It used to be that people accepted they might get photographed; now I think you need to be pretty brave (or hard looking) to take photos in public places at all, let alone candid photography. At best you may get jeered at by drunken yobs; at worst it can get physical and the police would probably 'book' the photographer for 'behaviour likely to cause a breach of the peace'. Not only the police like throwing their weight around; I've heard of people being ordered off railway stations for taking photos from the platform. I suppose these types have always been around - the ones who weren't prefects at school and need to make up for lost time! There just seem to be more of them these days.
