Those of us who, like Jon Snow, work in journalism have a high regard for the truth. It may not be attainable, but it is something you should always strive for. A journalistic coup is a daring denouement: the truth is revealed, villains unmasked and heroes vindicated.
The same could be said in the law, but perhaps with less conviction. Our system of justice is adversarial, which means that there are always at least two versions of the truth in play, a sort of jousting. Indeed, the earliest trials were trials by combat, not by truth. The truth in those days was assumed to lie with the strongest combatant. Now that our jousting is done in words, the truth is found to lie in the most persuasive combatant’s mouth.
