I don't really want to elaborate more on the Teoh Beng Hock RCI case. Now that it is over it is noticed that how and who did it is very similar to the recent Ahmad Sarbiani case. In summary, what is intended to be illustrated is that both victims are unfortunate persons suffered from third-degree interrogations used on witnesses making statements to the case.
“TBH had to face MACC interrogation heavyweights like Arman the bully [who would manipulate his witness to obtain evidence], Ashraf the abuser [who was Machiavellian in his method to secure evidence] and HH the arrogant leader [who would have no qualms in lying as long as the ends were achieved, regardless of the means employed],” the RCI report had pointed out.
This is what the RCI points out on the three men mainly responsible for Beng Hock's death. Now, approximately a month after Beng Hock's death, in August 2009 a letter containing the MACC letterhead purportedly written by some MACC officers do alleged the same thing above, but it mostly points to Hishamuddin Hashim, then deputy director of MACC Selangor. One testimony mentioned in the letter was in regards to how there were fingerprints of Hishamuddin on Beng Hock's belt and how Hishamuddin likes to intimidate people by holding by belt. This supposedly points to the fact that Beng Hock was threatened and forced to make a confession, fabricate one if there needs to be by threatening to drop him from the window.
After reading this Malaysia Today's document on events leading to Sarbani's death, part 7, you can see that it is related, though not exactly the same:
Now, this scenario together with Beng Hock's infers that these MACC people are forcing witnesses to come out with a statement that can at least prove their innocence, or shall we say "guilty until proven innocent", in this case, they whack you as if you are guilty from the start and along the way there are third-degree interrogations. If they are still unconvinced, they would try to throw you or make you jump off. The players are not the same, but the scenes are almost related and similar to one another.
