Yes, Deep Diver, I agree that this IS indeed a legal as well as an ethical matter. Also let's throw in a little common sense and courtesy as well, regarding people who are merely in the situation of shopping in a store, riding the escalator in a mall, eating in a restaurant, relaxing in a bar, simply doing their own thing.... It really is quite intrusive of someone who either openly or stealthily shoots photos of other people without their consent and often without their knowledge. To add insult to injury, then the image(s) might be posted on a very public website. Maybe ask first, then shoot? Give the person the opportunity to say "yes" or "no" and/or if they're right smack in the middle of the area that is really the subject, the chance to say, "oh, excuse me, let me move out of the way!" What makes anyone so special that he or she feels they have the "right" to pull out a camera and take a stranger's photograph?
