I wouldn't be much inclined to report the incident at all, though I would have refused permission for close-ups. But my own camera has a zoom, so I can take close-ups without actually being near people, and I do, sometimes even of children. I'm not a pervert, just an amateur photographer. The world is full of them; there are far more photographers than paedophiles. Other people just taking photos doesn't bother me in the least, though I'd be more protective of my child than of myself. Anyway, since this guy made himself known, I wouldn't be scared of him at all, and I certainly wouldn't have been wanting to smash his camera. There's no need to feel violence towards anyone who looks at you.
