Tell me the truth , who were you talking to at this date last year , what did he tell you? What did you tell him? Was this occasion the first time or the second time that you had heard or spoken this information?
I don't recall. So how the hell do you figure you could get me for perjury for honestly telling you that? You can't.
Honesty is still the best policy. It is not a crime to not remember or not know something. It can be construed as perjury if, for example, I said I was talking to you on such and such a date about this subject, then it was later shown I was wrong. It may be due to faulty memory, but if I swore it was the truth, then it could result in a perjury charge. If I qualified it by saying something to the effect of 'to the best of my knowledge and/or recollection', then I'd say you might not have a case; I'm not a lawyer, though, so you might want to ask Domer.
