Lookout how long do you think PC Collins spent looking through the window having been told JB received a tel call from his father saying "Sheila's gone crazy shes got the gun"? PC Collins was also told the farmhouse contained a number of firearms including a rifle and shotgun and thousands of rounds of ammo.
Do you think he pressed his face against the window cupping his hands at the sides of his face to get a good look when he was led to believe, rightly or wrongly, that a 'mad woman' with a shotgun might blast his face off?!
In all probability his observation of the kitchen was based on a fleeting glance from a safe distance.
I haven't seen an explanation from PC Collins as to why he initially thought NB was female. NB's hair has been given as a reason but I haven't seen anything from PC Collins about this. NB's pyjama bottoms had fallen down so it might be he saw bare legs and associated this with a female.
The bottom line is there's not a shred of evidence SC died significantly later than the other victims or that she moved significantly between sustaining the 2 gsw's.
The fact you and the CT keep peddling these old myths does nothing other than harm JB's case.
