Yes, ironically, he is the clueless one. People are on to his charade, but he has no clue. The Screwed One said Not just CPIB, all law enforcement cannot enter a Mindef premises or an SAF base, camp or facility even when murder occurs. They will be made to wait outside the gate until the place is "secured" by Mindef personnel.
Its common in many countries. The civilian police does not have jurisdiction over a military installation. This has always been the case in countries like the US, whose military system we follow. Don't know why he is so surprised by this. I have had countless Police come to the gates of a SAR to arrest or investigate some personnel in the camp. The guardroom does not let them in until its cleared by the Battalion DO, who in turn has to report and clear this with the Brigade DO. I have personally turned down the police request several times to interrogate my personnel. And they have gone away empty handed or not gotten everyone they want. If my guardroom let the police into my camp without my approval, they will do extras until the cows come home. Only Clueless will make a big deal and pretend like its some secret information only he knows. Its common procedure worldwide for the Police not to have jurisdiction over military facilities.
