Whistleblowing Is a Morally Ambiguous Activity on a Complex Concatenation

Whistleblowing is a morally ambiguous activity on a complex concatenation of grounds: It necessarily involves a betrayal of trust on behalf of a public interest which itself is on some occasions morally ambiguous. It indicts otherwise morally competent individuals and organizations concerned with being perceived as legitimate. Sometimes it arouses public opinion, a frequently contaminated process.
