There is plenty evidence. Two firearms trained spotters independently sighted a rifle, where there could not have been one, if the prosecution's case was genuine. Police were also in conversation with somebody from inside the farm, that they then made further unmet challenges to. Let's hope you never have to experience what she went through, in your quest to understand her actions.
Oh and I forgot... Bews fled in terror, after a backlit figure was sighted.
There is no evidence anyone was alive.
It was 'a trick of the light'. Which sources say Bamber saw.
The photo of the rifle was moved after pictures of Sheila had been taken. Or there were two rifles.
Conversation attempts 'met with no response'. Or was Sheila talking through a loud speaker ?
No one can give a reason why Sheila would kill 4 people then wait 5 hours before killing herself.
But appreciate Bamber's supporters like conspiracy theories
