@jnanian - I agree, but that just goes back to the issue of "intent". I don't ask permission to do street photography (not generally, anyway) but I also am not pulling a fast one, or intending to disrespect anyone. I think this intent colours my work, as it would anyone.
In kinder, gentler Canada, people might actually pause to listen to your "intent" statement. This seems to work even in Toronto but elsewhere?
