When all is denied

Someone once said, I deny it all including the truth. More recently, it was probably Joaquin Sabina in a song. Anyhow, taking the fifth might work out better sometimes, but obviously admission isn't the desired scenario in this case. When one has arrived at this point, either someone made up the horrible lie, or the error has been, in fact, committed. It is a slippery slope in all directions, seemingly and regardless. Error implies a mistake, a deliberate wrongdoing is not a mistake.
