Fortunately for governments and businesses, whistle-blowers are often deeply troubled people. I am hard put to think of a single whistle-blower who has prospered after exposing wrong-doing by their employer. To blow the whistle usually means sacrificing your job, jeopardising future employment prospects and, almost certainly, eventually, a serious loss of income. As Scots kids of my generation used to be told "no-one likes a clype". To that maxim might be added "and no-one trusts a clype either". At the end of day, most whistle-blowers were already fragile, unhappy or deeply troubled people before they went public. One of the first things an employer does after the balloon goes up is to attempt to discredit the whistle-blower. Whatever made the whistle-blower unhappy, odd or difficult to work with in the first place often makes this easier than it should be. Society's, our, lack of support for whistle-blowers makes it even easier to destroy those brave, or possibly foolhardy, enough to speak up.
