Now seriously... The characters in those pictures are absolutely random, with no intention to harm, abuse or get into their intimacy.
Pictures are taken in a public place by no hidden methods, photographer was in the view area of all this characters.
Nudity (if any) is in characters responsability and not photographer's as the public place was not designed for any topless or nudity presentation.
