Well, I for one am convinced by that explanation, and I now believe Quintavalle to be a completely reliable witness
(I particularly like the part where Quintavalle didn't recognise a woman's facial features, hair or stature when she was alone, because these facets were only recognisable to him when she was standing next to a particular other man.)
I thought it was the best description I have read on Quintavalle and it makes sense to me, logical sense. Haven't you ever seen someone somewhere and said to yourself, 'I know I know this person but from where?' It takes the association, such as 'it's so and so's friend' to allow you to remember.
yes, in some jurisdictions failing to report a serious crime such as murder is an offence.
Nara did not know a murder had taken place. She heard a horrible scream but had no way of knowing what caused it. Because she is probably someone who minds her own business generally she did not act on it. She has expressed regret over this.
