Basic requirement in journalism when "breaking" such stories is to hear the version of all parties involved before publishing the news.
For instance, in the Panama leak case, Nawaz Shareef and his off springs were offered to give their side of stories before publishing, but they ignored.
Question is, did Gen Bajwa was asked to give his version before this "revelations" were made by Noorani chap?
If not, then its just a smear campaign and this so called Journalist need to be made a horrible example. You call yourself journalist, play by rules, or face the consequences.
