Migrant mother was probably taken with consent...
No, it is not. When mother with child in hands runs away from bombing or murderes or rapists who attack her, she doesn't think about giving consent she run for life. And photographer doesn't ask her for consent. IF you ever was in that situation you would know (I mean was there not waching it on TV).
I know (because I was present in those situations) that during war in my country photographers were in shelters near streets waiting for people walking those streets to be shot by snipers. When people were shot those photographers made photos (another question is what to think of a man who see another man who dying in front of him and doesn't try to help...). They publish photographs in magazines, made exhibitions, etc... one word earn money. Nobody asked consent of those shot people can those photographs be published.
Now: Because in one state live people with different cultural, religious, moreal, etc... backgrounds and opinions, there is only one thing which can be done. That is to make a law which will be valid for all those people and everyone should respect it. On the other hand all those people must realize that they make compromise and accepting that law they reject some of theire moral, religious, etc... rights. Concequently, if in one state by law people can be photographed on street, and theire likeness can be published and at the end bring money to photographer, that law is only thing which should be looked at. Because if you give one individual or group to act following theire moral, religious, etc... rights, you must give same right to every other person or group. And as we all have more or less different thinkings about different issues, we will never agree. So, our life would become impossibile.
That is, however this sounds wrong, in case of photograph of that man, law is only thing which should be looking at. That man, going to public, accept that he make compromise with his rights to privacy, and he must be aware of that fact.
