Well, I completely agree with you, but modern society unfortunately doesn't. At my father's university, professors aren't allowed to be alone in a room with a student unless the door is open, for fear of false accusations. Even at my school here in France, where (aside from strict rules against religious representation) political correctness is about 40 years behind American levels, I'm not allowed to be in a room with less than 3 students.
I remember years back when I was working in retail, one of my coworkers got a public thrashing from a customer for the following incident: she (my coworker) saw a little girl of about 8 wandering around the store without an adult. This coworker is in her early twenties, works at a school for special-needs kids, and has a very motherly nature. She went up to the little girl and asked her where her parents were. The girl said her mother went to "a grown-up store" and would be back soon, so my coworker stood with her for a while and showed her a few computer games. Five minutes in, the girl's mother comes in with a Victoria's Secret bag screams "KATIE!" (don't remember the actual name) at the little girl when she sees her with my coworker, runs up, and yanks her away from the computer. She proceeds to yell at the little girl for talking to a stranger, and then rips into my coworker with things like "You should ****ing know better than to talk to a child who's alone! I should call the police right now!" Luckily, the manager came in and diffused the situation, but my poor coworker was mortified for an hour or two after that.
As long as things like that occur, I think I'll keep my camera to myself anywhere near kids, thank you very much.
