Of course I don't know anything about him nor do I have any background on events due to which he was fired.
It appears from the article that he was trying to blackmail Army for an honor which he may or may not have deserved. If Army is involved in the death of Alvi, then I am sure Great Zardari, the President of Pakistan will bring the relevant people to justice. If Great Zaradri, the President of Pakistan does nothing, then obviously the story is not true.
