BB,
What I said about Malaya is based on a year's archival research and interviews with surviving terrorists and intelligence officers, conducted 10 years ago (which I am willing to share with you - including a considerable amount of documents from the CIA's own archives).
What I didn't say was it didn't happen; what I did say that it was prohibited (I have a copied of the Order signed by the Commissioner of Police) and was not an instrument of state power (unlike the present matter) - why? Because in this contflict it was completely unhelpful. Once you tortured a CEP/SEP (who was subject to the civil police code), you could not turn them and use them as a source, with any degree of success. Fact.
