How about
f) a convincing explanation as to how Sheila - with no experience of firearms and mental health/co-ordination issues - would have been able to reload a complex weapon twice and fire 25 bullets accurately
g) a convincing explanation as to how Sheila was able to overcome, and impose severe injuries on, her father who was a foot taller and physically far stronger than she was
h) a convincing explanation of JB's behaviour following the call from Neville. Specifically to cover why he didn't call 999, why he didn't go to the farm immediately, and why he called Julie if it wasn't to create an alibi for himself?
a - d are based on aspects of the case where it might be possible to undertake new tests etc capable of securing a CoA hearing. I'm not sure f - h above could be advanced in this way. F - h were all aspects of the case that were thrashed out at trial and according to Ewan Smith above the jury was primarily interested in the silencer/blood evidence. I think the only people capable of determining what constitutes a "convincing explanation" for f - h would be a jury but I'll give it a go:
f) There's no evidence SC handled firearms in adulthood. She left WHF at 17/18 yoa and returned infrequently. However we don't know what went on during her childhood. Growing up on a farm surrounded by firearms and those that used them signals to me that she would have more idea than most. When I started fending for myself I can't ever recall my parents sitting me down providing detailed instructions on all manner of things from roasting a chicken to planting bulbs but somehow I knew how to do these things. Did my parents explain at some stage or did I simply observe consciously or sub-consciously?
Yes SC had mental health issues but afaik there's no evidence of any learning disability preventing her from loading and firing a firearm.
Where's the evidence SC suffered co-ordination issues?
Where's the evidence a .22 semi-auto rifle is complex? It's perceived as complex to most in Little Britian as its alien and something they have little or no knowledge of. Ask most Yanks and they will tell you something different.
Where's the evidence accuracy played a part at WHF? June was prone in bed when initially shot and slow or immobile thereafter. NB's facial shots and head shots were fired when the rifle was within inches of his skin. The twins were asleep in bed.
g) How did Andrews overpower and murder Lee Harvey with a pen knife? See image of pair below.
h) Behaviour is very subjective. If JB received a call from NB saying "Sheila's gone crazy, she's got the gun" then I think his reactions are within the 'normal' range ie trying to call back to seek further info from NB as to what was required and discussing with JM beforehand.
