It's certainly difficult to comprehend why there would be such a cover up but I do believe life is stranger than fiction.
I try to imagine why the likes of Ainsley agreed to cover up evidence and point the finger at the innocent Bamber, however perhaps he was just a corrupt copper willing to scratch a mates back in return for some back scratching of his own
I have always thought there was an outside chance that a few at the top of EP may have covered up evidence rather than have to publicly admit they had been right the first time and JB wasn't guilty after all. No one likes to look that much of a fool but it us a bit far fetched.
I am curious as to how the rest of the raid team and others who accepted Sheila was guilty for what Roch has said was readily available evidence, were closed down and have been kept quiet ever since?
ACC Peter Simpson was top brass. He created downward internal pressures, by wanting Jeremy Bamber to be investigated for the killings (in attempting to appease Robert Boutflour). The detective chosen to oversee this - DCS Michael Ainsley happened to become close-knit with Robert Boutflour to the extent he called him 'Bobby'. DCS Mick Ainsley was able to make use of the fact that DS Stan Jones hated Jeremy Bamber and was gunning for him.
Jeremy Bamber himself, seems to have done himself no favours. I think the behaviour that gets attributed to him is a combination of three factors. Real behaviour (for which he only has himself to blame); perceived behaviour (in the minds of suspicious and judgemental people); and made-up behaviour (deliberately designed to blacken his name further by exaggerating etc). Perhaps it was easy for some police and others to show little sympathy or interest regarding his plight.
The conviction has plagued Essex Police for 32 years. Knowing what they know now, if they could go back in time and revisit the immediate aftermath of the killings - I very much doubt they would make the same decisions.
They would either come clean from the off regarding any complications in the farmhouse - or at the
very least they would send the vultures packing, when they showed up with their bullshit grievances and theories.
