The Malaysian authorities will have red stuff on their hands if it turns out one of the pilots was being hounded by the judiciary.
I have no inside information, but it's not easy for a Malay to be honest about his religious beliefs or lack of them. Nor is it easy to be an 'anti-corruption campaigner'. Can upset some people.
This to be taken with a large pinch of salt and it's not my opinion, only based on what I see on the web.
