Yes... but what you hear on NG may or may not be true when it comes from anyone other than LE. IOW, those rumors started because of what Elaine said, and she was not clear in her answers. At the end of that interview, there is nothing definite, just that she believes it was inconsistent, and that she does not know if he was asked to take another poly. Before that, she thought he failed, and then she didn't know for sure.
Personally, I am not going to take anyone's word for it unless it comes straight from LE.
As far as him not refuting accusations, why should he? He knows they are not going to believe him anyway. He could tell him the sun rises in the east and sets in the west and they would call him a liar.
That rally was set up to harass and intimidate him... it was not to get answers. What made them think he would come out and talk to his ex-wife and son in a whole crowd of people? That's idiotic. If you want answers from someone you meet with them in person, without 25 other people looking on.
I can't imagine what they hoped to accomplish when they were standing out there in the cold holding signs in front of an empty house. Lot of good that did, since he wasn't even there.
