No, then still not. You missed the point. Lying is not the same as saying something that isnt true. Lying means you know it isnt true, at the time of saying it. Even if you knew my name for a fact, and knew I said my name is something else, you still dont know if I said a lie. All you know is I said something that isnt true. There is never 100% certainty of someone lying. If you dont get that, you either dont know what the definition of lying is, what 100% means, what certainty means or how the brain works.
No I didn't miss the point. To be honest I thought it a rather silly example that only deserved a silly response.
It doesn't matter if 100% certainty is there or not, if there is a situation where someone is inclined to tell a lie then we can say that, beyond reasonable doubt, they were lying due to having an ulterior motive, ie for fraudulent reasons. Technicality be damned.
On numerous occasions you have said that Sean Murray lied. If he was to say that at the time of making his comments he believed them to be true, would that suffice?
