Mahathir should be charged if he is found guilty.

If Nixon who was the President of the most powerful nation on earth can be impeached and charged for his role in the Watergate scandal, I cannot see why Mahathir who is a retired former head of state cannot be charged for his role in the fixing of the judges.According to a report in Malaysiakini ,Mahathir challenged the govt to charge him.
If the govt is serious in getting to the truth of the Lingam scandal, no stones should be left unturned to expose the insidious conspiracy that allowed a less than capable judge Tun Ahmad Fairuz to be appointed as the chief Judge over the more popular and capable Judge, Datuk Abdul Malek.
Since Mahathir has thrown the ball at the govt's feet, Pak Lah should have no hesitation in taking up the gauntlet. The royal commission report has already provided an insight as to Mahahtir's role in the scandal.If further investigation can be unravelled to prove his pivitol role in the scandal then the full force of the law should be brought against the former Premier irrespective of his former status.
His former status should not provide him with any form of immunity if there are grounds to charge him for subverting and conspiring the appointment of Judges.
Pak Lah should not be cowed by Mahathir's challenge and to prove that he is serious in cleaning up the Judiciary,the Attorney-General should be directed to investigate the revelation in the Royal commission of the Lingam Scandal.
