I think that Mitford's view is correct because sometimes the truth is not fully found unless someone uncovers it. Also journalists who do uncover these stories may also end up doing more good then bad. For example in the 1800's there was this American journalist who went by the name of Nellie Bly. Bly faked insanity so she could go undercover to investigate the allegations against the Womens Asylum on Blackwells Island. She faked amnesia and was tested by many doctors who all claimed she was insane. It was then that she was commited into the asylum. While she was there she was able to truly see the brutality first hand. Ten days later she was realeased afterwards she released her report on her findings. Her report became an istant sensation
