Adam, I don't get where you're coming from - so cannot provide you with the type of answer you are seeking. My guess is that the incident may have flared up several times during the night. Or it may have deteriorated extremely quickly, without sufficient prior warning signals. I doubt Nevill could have foreseen the grave and lethal danger that his family were in. Otherwise, perhaps the situation could have been diffused earlier, by timely restraint or outside intervention. Clearly it wasn't. I do not see significance you are attaching to the arrival of CA7 (for reasons already stated).
I have asked the same question 4 times. You have failed to give an answer.
You say Sheila could have continued carrying out the massacre after the police arrived. Then refuse to say what you believe she could have done.
A lot of the 14 things on my list, Sheila may not have done. Such as shower, write a suicide note, change clothes, read the bible and put the silencer away. These are all things supporters have made up and claimed Sheila did. You had the option to discard any of these so she had more chance of completing the massacre in the time scale before the police arrived.
You also had the option of discarding the made up claim that Neville called the fifth furthest away police station. Which even Bamber does not believe happened. This would have given Sheila 38 minutes to complete everything. Rather than 22 minutes.
Just like all supporters you discarded nothing. To be fair, unlike other supporters you then attempted to justify this and said Sheila continued after the police arrived. Which is a new theory. But then didn't say what you believe she could have done and tried to deflect attention onto me.
