Seems like I’ve generated a bit of a storm here. To summarize, it helps if you look non-threatening. It helps if you ask first. It helps if you have a female an/or a dog with you. At the first sight of trouble, grab your gear and get the hell out. Cops are not helpful. Law and rights be damned, no one wins a fight with an angry and protective mama bear when it comes to her cubs. Do not disregard signs on private property (malls, restaurants, etc.) I would not recommend following the advice to “sneak” pictures with your cellphone. This could result in more than a long talk with the cops if you are caught. Plus if you have to sneak pictures, perhaps you shouldn’t be doing it in the first place. As far as posting kids pictures on here or anywhere else, you are getting into very dark territory. In my business, no model release means no posting, sale or display. Even have to blur out faces of bystanders. Talks is cheap, but you only need to be sued or arrested once. And how does one answer the question “what are you going to do with the pictures?” And so on. Maybe it’s just wise to not photograph kids, period.
