Bamber's narrative on the night was/is -
There were fostering conversations.
He had left a loaded rifle out after going to shoot rabbits.
Nevill had rang him & said 'please come over, Sheila's gone crazy & she's got the gun'. Before the line went dead.
Sheila was a 'loony' who knew how to use all the weapons & should be locked up.
----------
The judge said in his summing up, Sheila being non responsive regarding the aledged fostering conversation, means it cannot be used as a motivation for her aledged actions.
This is damaging as the judge is asking the jury to believe Sheila shot her mother, father & sons in bed for no reason.
