He did have over a year to persuade people not to change direction. Or leave the case/EP in protest.
But didn't.
Changes was made to policing after the Bamber case…….issues with police handling of the Jeremy Bamber case led to an official review and the introduction of tightened national procedures for major investigations and crime scene preservation.
The initial police investigation into the 1985 White House Farm murders, where five members of the Bamber family were killed, was widely criticized for a "bungled" approach and significant errors, primarily because the scene was initially treated as a MURDER SUICIDE and not secured as a potential murder scene.
Key problems identified included:
The senior investigating officer (TAFF) wrongly concluding it was a murder-suicide, which meant normal murder case procedures were not followed.
Following a report on the investigation, the Home Secretary ordered a review of police procedures, and Her Majesty's Chief Inspector of Constabulary conducted a separate review, resulting in 18 recommendations for the police service and reinforcing standard procedures for managing major inquiries. These steps led to improved protocols for handling evidence and securing crime scenes.
When Taff told and briefed Cook it was suicide and gave him the run down of Bambers phone call from his Father, he was already relying and bought into Bamber’s account that Sheila had “gone crazy with a gun.” Having accepted that and what Bamber had told them, This acceptance obviously shows with his brief twenty five minute cameo visit and this then filtered down to those under his command.
It should be obvious to anyone with half a brain the investigation was seriously lacking, a multiple homicide/murder of this scale should never be approached with tunnel vision, its basic Management progress and the thing I was taught in the mines, tunnel vision is replaced with funnel vision!
