No offense, But I often wonder how often people are taking photos of others with out consent. I mean it makes one aware of others who like to carry around a bulky camera all the time. Like this guy on the subway was once just snapping shots from the end of the cart with out anyone noticing. And no one caught on because you know, cell phones.
Just figured I'd mention the reality of this even though your intentions were good in sense of adding to the message you wanted to spread.
