But a consummate liar, after enough lies have been told, convinces no one for ever surely? And they must know this, because they're aware that every one else was witness to what actually happened and what the real truth is. So we can assume that the truth of the matter is too difficult or unpleasant for them to live with, and they have to "rewrite" it in order for it to be palatable enough for them to carry on and live with. My point is, do they acknowledge, deep down and in private moments, the real truth or is the power of denial and self preservation so strong that they actually believe their invented version? And, for example, is this how BJ et al, have salved their consciences; knowing that the majority of the country recognises them as the consummate liars they are; but they've told themselves the narrative that "x" never happened, it was only the lesser lie of "z".
