I think it's a complete fiasco of the Malaysian authority, especially the defence minister himself.
Malaysia civilian and miltary radar knew about the diversion by the pilot, but never disclosed until questioned by the media, as Vietnamese & other search teams spent so much resources in the gulf of Thailand, and south China seas, and strait of Malacca.......
The Malaysia authority knew there's nothing there, and keep lying until the American and British pointed out that the jet kept travel for 5-6 hours southbound towards the Indian ocean, then only the search began to focus in that area. Mr Hishamuddin knew all these fact but never disclose or being transparent.
Mr Hishamuddin is well known a talk big Malay Supremacist, cousin brother of the Prime Minister, he only knew how to show his "keris Melayu" (Malay sword) in front of his party assembly to threaten other races (if disobedient to his rules) !! History will prove that he's a complete failure period.
不可否认的是他们游行示威是想逼出真相，好move on with their life。真相是他们move on的前提。
但也许马来西亚真的只是太笨，没有隐瞒真相。但who knows
他们反正闲着是闲着。找点事做。可以理解。不要诉诸暴力就行。好过自己闷着想得太多得不到发泄而自杀。
庆幸暂时无人自杀。很坚强。
