To be fair, there are people that get hostile even if you look in their direction (not even at them...), yelling "He, was guckst Du?" You know.
So, people are strange; it even does not need a camera to bring that out.
Have you tried telling people on street about what you are doing? Not necessarily effective if someone tries to beat you up though.
Thats true, come to think of it. That would be a great photo projekt.
Well, i am from Germany and shoot Street. I dont much care about our laws. One of my rules is not post "local" pictures at local web-sites, so the stranger have no options to recognize thereselves and make probably trouble....
I post my pictures around the world like e.g. flickr in different Street-Groups.
