The case of 'Raiwind Davis'

One was quite amused to hear Punjab Chief Minister, Shahbaz Sharif, during a press conference the other day, accusing the federal government for engineering the acquittal and manipulating quick exit of the alleged killer of two Pakistanis, Raymond Davis to the US.
The junior Mian Sahib, like his elder brother and mentor, have a great and canny sense of timing to scoot to a foreign location, to escape and avoid a difficult situation, rather than facing and confronting it, like men of grit. On the crucial day when Raymond Davis was to be tried in a specially constituted court at the Kot Lakhpat jail and later to be released, the Sharif brothers had conveniently decided to be out of the country, in a seemingly, innocuous effort to absolve themselves of any part of theirs in the sordid Davis release affair.
During the above press conference, Shahbaz Sharif, with a poker face, took great pains to absolve himself and the Punjab government of any knowledge, wrongdoing or involvement in the Davis release affair, expressing complete ignorance over the issue as to who engineered the acquittal of Davis and planned his escape. Shahbaz Sharif, to demonstrate untenable veracity of his contention, offered to resign if anyone proved his or his government's involvement in the Davis release saga.
The following day, a well-known journalist, Najam Sethi, in his TV programme challenged Shahbaz Sharif's contention, claim of complete ignorance and non-involvement of the Punjab government in the Davis release affair and invited Shahbaz Sharif to the show where he would provide and present irrefutable evidence, confirming involvement of Shahbaz Sharif and his provincial government.
If Shahbaz Sharif is a man of his word and worth his salt, he should accept Najam Sethi's challenge and prove his innocence and ignorance over the issue or, otherwise, resign from the post of chief minister of the province, as promised in the above mentioned press conference.
