I was discussing that, some time ago, with a female friend (I am a male) who also loves doing street photography. We talked about how difficult it is for a man to do street photography, specially around places with a lot of kids, as you will always receive strange looks or even threats. If you're a woman taking photos? Probably a mother or mother-to-be, if you're a man? Pedophile.
I wonder if there are that many people exposing themselves to kids as the security lady said in the article. Seems like an excuse to justify the action, or something that happened once and they are overreacting to it...
