If I found a bunch of confidential documents I'd contact the owner of the documents and tell them, not the local press.
Maybe. OTOH it might be better to give the documents to the people they are referring to. Much of the information in the case notes of social services and similar organisations are 33% very selective truths, 33% gross exaggeration and 33% outright lies. It might be beneficial for people to see the official re-write of their personal histories.
