But one's guilty conscience would be biting on the inside. I believe that would ultimately lead to depression. Such is 'Damned if you do, damned if you don't' situation.
Shouldn't a law be legislated to protect whistle blowers? And if there is, what should be contained in the law?

Indeed. Materialistic? For me, I view the problem roots from capitalism. While it is good for the economy to a certain extend, it does tend to disregard important social issues and morality/ethics.

Idea is, if a law exists, there can at least be a legal platform to whistle blow, and hence providing a more substantial case in the court. Previous court cases involving whistle blowing, such as the 3 engineers from BART, eventually lost the case even though their act saved lives.
Sure they've done remarkably for the society. But at the end of the day, they've lost their jobs. A case of 'Buat baik dipanah kilat.'
