So the PDRM have not been able to verify the contents of the unsigned letter by MACC officers but to most normal folks, very few expect the police to point the finger at the MACC as the latter have the power to point back at them.
Such is the situation as far as CREDIBILITY of government institutions is concerned.
You can read a selection of citizens' views on the MACC letter in the malaysiakini article headed Not just another poison-pen letter.
So it is not me with a poor impression of the proceedings - maybe malaysiakini is also a little biased; but not a single writer has expressed much faith in the goings-on.
What of the 5 oversight committees with 42 prominent members? It appears that they are prominent by their absence in the murder of Teoh Beng Huat. A body like the MACC should have only one oversight board like a Board of Directors in a company and they must have the authority to take action and not be dependent on instructions like from the PM.
