Yeah, I agree! I've not see any of his photos, despite having seen this article a good few times now ... But it does sound as though he has an "interesting" taste in subject matter!
I have taken photos of homeless people, in fact I took one just the other day in the metro in Paris, but really only to be seen in the context of the other shots from my day trip! I certainly wouldn't go out with it in mind to shoot the homeless, and there is no way in the world any photos like that would ever make it into a frame on the walls of my house!
