Whoever said that pathological liars aren't aware of validity of proof.
A thief knows more about locks than the lockowner or perhaps even lockmakers.
Disagreed. When exposed, they tend to react irrationally (i.e. make mistakes)[1]. As a good example of that, take a look how Quickscammer reacted when he got exposed. He lied that he got a 2 (or 3?) day ban, which is ridiculous and as a lie absolutely stupid given that it can be trivially disproven (which it was by BadBear).

[1] Then again, not every pathological liar is as smart as the one next to him. I can't draw to any generalizations here.
