For me, documentary photography has always come with great responsibility. Not just to tell the story honestly and with empathy, but also to make sure the right people hear it. When you photograph somebody who is in pain or discomfort, they trust you to make sure the images will act as their advocate.

I don't see myself as being injured by a landmine or the Taliban I was injured by ignorance and hatred. When people do these things, they want to create more hatred. Fight it with love and education.
