I feel much the same as you, there is way too much in his past interviews for anyone to believe he has suddenly become this helpless, frightened man and the lack of use of the panic button is quite unbelievable.
It also doesn't wash with me that this 'helpless, frightened man' was so concerned all the time about being broken into by an intruder, that he managed to sleep perfectly ok with the balcony doors open. I think I've said before, even I would have some difficulty sleeping like that as I would just naturally feel quite vulnerable. How come he didn't?
