OK. Do you agree that if she was shot in an 'alleged struggle' (as a cover for having been shot accidentally), the police at the scene (when it actually occurred), would have likely experienced stress, as to how to proceed? Especially given that it was the alleged murder weapon. Stress that could impact upon decision making - which was effectively on the hoof.
I do think some police will have baulked at the idea of framing Jeremy Bamber. However disconcerted that individual officers may have felt, bar raising their concerns internally - what other options do they have (options that will not effectively destroy their career?). It was the ACC who sanctioned the investigation of Bamber - therefore the pressure was created from the top of the command structure.
No, I don't agree at all - it would have been accidental and I certainly don't think it would warrant the framing of Bamber. Yes, there might have been an enquiry but given the circumstances, a killer was killed during a siege situation, no careers needed to have been ruined. However, if it is hard for you to believe that Bamber would try and pass off two shots to Sheila as suicide, why would you believe the police would?
However the two shots happened, Bamber would have little choice in going ahead with his plan as you say what other option would he have'?
