Police Report against IGP and AG

Contrary to my earlier posting, the police report made by Anwar Ibrahim on 1st July, 2008, against Musa Hassan, the Inspector General of Police, and Abdul Gani Patail, the Attorney General, respectively was pertaining to the latter withholding facts against Rahim Noor, the former IGP, for assaulting Anwar in the eye whilst under police detention.
Anwar claimed that both Abdul Gani and Musa were aware of the assault by Rahim against him on 20th September, 2007, at the Police Headquarters in Bukit Aman, but chose to conceal the incident from public knowledge. The public only learnt of the incident when it was brought up to the attention of the court during Anwar's trial.
Abdul Gani and Musa were also alleged to have conspired under the direction of Mokhtar Abdullah, the former AG, in preparing an undated medical report on the injury sustained by Anwar which was inconsistent with the nature of the injury.
If that could happen once before, what assurance could we have that such similar incident will not recur ?
