Abbie,
I saw a very funny incident at the Pyramids where someone refused to pay . I also was tugged by the sleeve to take some pictures when I looked round it was two local policemen holding weapons , yes it could have been problematic .

So you've checked on the point of law but how would feel if you were outed or otherswise by someone exercising their right to take pictures of you totally ignoring your rights to privacy and respect ?

I guess I'm more sensitive to the issues as I had to take care as a professional who I could include or needed to exclude from pictures , I know how sensitive people can be about this problem and always tried to respect their wishes , I'm sorry more people don't consider that . The rights of individuals is a two way situation not a one way one .
