Were the police there? Was the trial judge there? Was the prosecution there? Was the defence there? Were jurors there? Was the pathologist there? Were the defence experts there? Was the FSS there? We know no one was there! No one needs to be there to understand what happened; its the reason soc reconstructions are carried out but in this case to date it hasn't happened. When it does happen it will show exactly what happened and it will not include all the nonsense you post up.
Do not lecture me about nonsense posts. Your claims as to the marks on NB are factually incorrect.
The true beginning: 1950sThe first widely adopted metal spinal fixation device was the Harrington rod, developed in 1953 by Paul Harrington.
Although technically a rod, not a plate, it marks the start of modern metal spinal instrumentation. It was initially for scoliosis but soon used for traumatic spinal injuries as well.
Expansion to trauma: 1960s–1970s
By the 1970s, Harrington rods were routinely used to stabilise burst fractures and other spinal injuries.
This is the first period where metal implants became standard for fixing spinal trauma.
True “plate” systems: late 1970s–1980sSegmental fixation systems (Luque wires, later pedicle screw–rod constructs) emerged in the mid 1970s and evolved into the plate and screw systems used today. These were not in your search results, but historically they follow directly from the Harrington era.
So it cannot be an old war wound fix and if it was a rod fix it would not have the features which are presented and if it happened later it would have been common knowledge in the family and JB would have known.
