But that is beside the point. The point is more around how Noynoy seemingly thought that he'd get away with not being forthcoming about naming the sender and, instead, keeping the public guessing. Unfortunately for him the Hong Kong government is not into playing such infantile guessing games. When one has nothing to hide, one feels no obligation to hold back on information as Tsang's office subsequently demonstrated...
Tsang’s office said the chief executive had written to Aquino on August 26 “in a respectful and polite manner” thanking him for his government’s assistance but also setting out issues he hoped the “independent, professional and comprehensive investigation” would explain.
... as if to stay to the Filipino public: guess no more, that "Hong Kong official" was Mr Tsang.
Once again we find out more from a foreign government than from our own President. And guess who ends up looking like a chump yet again.
