This case has genuinely made my anxiety worse, because how is it possible for someone to look and behave completely calm and normal and then do something like that? How can you tell if the person in front of you is just an introvert / socially anxious person or a potential murderer? Who was he? A psychopath?
For example when I watched interviews with Ted Bundy, it was immediately obvious to me that he had narcissistic traits and that something was off about him. But with Watts … I know a lot of guys that are calm and shy like he is.
