2007.04.12 : I blew the whistle on the whole thing.
我把整件事都抖落出来了。
名词whistle的一个主要意思就是警哨、警笛，动词短语blow the whistle（吹哨子）沿袭下来的意义就表示“告密，揭发，检举（不正当行为）”，是个俚语。由此形成的一个名词“告发”就是whistleblowing，“告密者”就是whistleblower。
例句：
Someone has blown the whistle on his doctoring the accounts. 有人告发他伪造帐目。
It's said that those government officials who had blown the whistle also got transferred.
据说检举这个事的政府官员也被调职了。
海纳百川，有容乃大；壁立千仞，无欲则刚。
