The act of telling a lie is nothing new. In the English language the word “mendacity” has hardly changed from its ecclesiastical Latin origin, mendacitas or 'lying'.
Individuals lie. Often they are only fibs with harmless intent, like those that preserve innocence about belief in the Easter Bunny.
Governments lie too, sometimes with minor consequences — to escape political accountability, to bolster popularity, or to avoid public retribution.
There are different classes of mendacity. Society can tolerate political and bureaucratic lies, up to a point. But when the consequences are too injurious — that is to say, when the policy makers or their proxies are reckless enough to have “gambled” (to use Stan Marshall’s word) and lost, or worse, possibly having contrived the fundamentals going so far as to assure billions in profit— a minimum expectation is that the culprits will be held to account.
