"Don't quote me on that" is such a wonderful phrase. It is an incredible ploy to say anything and everything and yet get away with it by disclaiming what has just been said.
Of course, once disclaimed, the listeners are then free to go ahead and repeat what they just heard from a reliable source, but just don’t quote them on that.
If the information turns out to be true, then the original perpetrator gets to say “I told you so”. If the information, however, turns out to be false, they could not be held liable.
It’s a Win-Win situation.
