Yet you're quite happy with the concept that any anomaly that has come to light in the secondary investigation that gunned for JB, is merely a benign mistake. All of the mistakes in the scondary investigation (which appear to many as resembling tried and tested corruptive practice among 80's police forces), are perfectly acceptible...
Whereas any mistakes that went on prior to JB being suspect in the initial investigation are representitive of poor professionalism on the part of the officers concerned.
The widely accepted version of events regarding the initial poor investigation is in my opinion a smokescreen for corrupt practice. Holding their hands up to poor investigation effectively lets EP off the hook and places the blame on Taff Jones who is not able to defend the initial investigation.
As you observe the "mistakes" made in the secondary investigation could all be explained with reference to the "tried and tested" corruption of 80's police practice.
Given what is now known and undisputed regarding police corruption, and the many wrongful convictions of this era which occurred because of this widespread, some would say institutionalised, corruption, I am constantly amazed that anyone believes the fanciful and implausible reasons given by the police for these discrepancies.
The police of this time are proven liars and manipulators of evidence and as such where discrepancies occur that can be explained either by corruption or genuine error, it is reasonable to infer that it is more likely to be the former rather than the latter, especially so given the continued refusal of EP to hand over evidence requested by the defence.
Only one side in this are unwilling to have all evidence out in the open and the implications of this refusal are surely that EP have something to hide.
Many posters make reference to the many "myths" that there seem to be about this case and in my opinion the biggest myth is that the first investigation was botched. It is more likely that the entry to the farmhouse was botched. The covering up of the botched raid led to circumstances that made it expedient for EP to blame Bamber and therefore the initial investigation needed to be discredited as a damage limitation exercise.
Conveniently the blame for the supposed botched investigation could be placed on the deceased "Taff Jones".
I don't believe that their was much to investigate anyway really . The events throughout the night and the knowledge of being party to what was an obvious siege that night meant that the police knew exactly what had happened. They hadn't sat outside a silent house with no movement all night without approaching until 7.30 and it is absurd to think so. The belief that Bamber kept them away with his manipulative ways is not tenable and stretches credulity beyond breaking point.
There was nothing to investigate because the police were witness to the events that night .
