The Crown were weak.
The rope for instance. I was not aware that Gravity and rope was brand dependent. The Crown prosecutor should have shut that down for the ridiculous argument that it was.
As if the brand or type of rope is going to have any bearing on the effects of gravity and the human body.
Also the Jury only need ask themselves. Why does a Doctor, or anyone for that matter make an attempt at a concealed web search for the effects of strangulation. There is no explaining away that search by him.
The police investigation was weak. They should have swabbed the knots of the rope for her dna, the absence of it, and likely finding of his dna on the knots would be crucial.
If the victims neck was not broken by the hanging, then why were there no signs of clawing at the rope as happens during airway obstruction.
Lastly the bruising from hanging vs strangulation is quite different and distinctive, it really feels as though the forensic case was seriously let down somewhere in the chain. Either in the gathering of evidence or the presenting of it in court, somewhere the Crown was weak (that rope argument was telling in terms of how weak the prosecutor was).
