Imagine that a spy defects to another country and reveals, among other things, that he had been ordered by his superiors to lead an operation to infiltrate the society of a third nation to influence the result of an upcoming presidential election. The goal of the operation was to unseat the incumbent president.
Instead of calling on the government to fully investigate the claims, as would be reasonably expected, the nation’s opposition politicians react to the disturbing news by immediately launching an all-out attack on the defector. They feverishly denounce his testimony as a pack of lies, even hinting that he is part of a global conspiracy.
