There's some ambiguity between the Wikipedia page and the following documentary around the 21:00 mark: https://youtu.be/hakgangq1qo
There is no ambiguity, Steve. The so called "documentary" that you link is "true crime drama" bullshit. You rely on information from the any source that confirms your own knee-jerk bigotry. In the booklet linked earlier in the thread the type of misinformation spread by "true crime" drama and the those who watch them was specifically referenced;
ITV Real Crime"In 2008, ITV broadcast a 45 minute film Angel of Death
about Colin. The programme has been repeated on
Freeview channels and is easily available on internet
sites.
Angel of Death comprised a welter of inaccurate,
unsubstantiated claims about Colin and the facts of
his case concentrating solely on WYP’s distorted
version of events. These included the fiction that early
police enquiries on the wards led them to arrest
Colin. No evidence exists to support this assertion.
The film omitted mention of the defence case. Instead,
a psychiatrist who had never met Colin opined at
length how he could tell he was guilty purely from is
‘body language’ in filmed police interviews. Likewise,
Det. Ch. Supt Chris Gregg never met Colin but was
able to expound extensively about his supposed
innermost thoughts.
The ‘facts’ broadcast in this film are often deployed to
disparage Colin on social media. The dissemination
of misinformation about Colin’s case is particularly
prevalent among followers of the current fashion for
so-called ‘true crime’ stories."
Ethel Hall's death was 3 weeks after the so called 5.15 prediction. There is no ambivalence. True Crime you-tube videos are not sufficient grounding for opining and debating on possible MOJ's, Steve. You have demonstrated this in spades.
