That's one thing that strikes me about him: sheer brass neck. He has shown that quality throughout, even questioning the police about forensics and accusing them or the laboratory of corruption or contamination! Then there is his brass neck in standing up and telling a load of blatant lies such as that Joanna showed sexual interest in him, that there was no struggle, that he was only trying to calm someone he strangled to death and that he can't remember any of the facts and events that just might put him in jeopardy. There is no recompense, nothing that can help, nothing that can fix any of it, give Joanna her life back or mend the lives of her parents, brother and Greg but he could at least have told them truth if he had any remorse and any decency in him.
