Establishing a pattern of shiftiness would not make the actions in question less questionnable.

If I hear a surprising claim from a pathological liar, I'm also less likely to believe it, not more!

True, but saying that doesn't actually give it weight. And they aren't making a claim here, they are denying an accusation. My saying "Hey, pathological liar, I think you're Santa" and them denying doesn't make it more likely they are Santa.

That's fair! I overstretched my analogy a little :)
