The truth protects itself, right? Truth tellers are protected by the sheer fact that their story remains the same, no matter how many times they tell it. Written records, signatures, videotape, all kinds of PROOF to back you up endlessly, if you know what you’re talking about, right? Not so.
Actually, the American government (and other governments of the world) have made the truth a matter of national security. It must be protected by the powers that be. Telling the truth means that someone else has an unfair advantage over you and governments need to hide it in order to protect their interests. Which of course, we are told, are our interests. (I’m wondering how $5 a gallon gas prices are in my interest but that’s another story.)
