Yes, that’s fine, but in 1985 things were different to nowadays when armed police show up to every incident. In 5 years I only saw it once. It suggests to me that Bews must have seen Sheila armed with a rifle at the bedroom window. I can’t think of any other reason to run back to CA7. If he didn’t see her in the window then he had no reason to call up the cavalry. Besides, Bews lies every time he opens his mouth!
As a former police officer do you have access to the operations/training manual? Surely this will set out under what circumstances firearms are called upon?
If you think PS Bews saw Sheila armed with a rifle at the bedroom window have you any ideas why Bamber didn't mention in his witness statement, police interviews, trial, 2002 appeal, 2012 submission? And when he exchanged correspondence with Colin Caffell post trial, where Colin asked him to reveal what happened, why didn't he mention then?
Seems to me PS Bews is a peripheral figure. Maybe he just can't recall all the detail as opposed to deliberately setting out to deceive.
