I am not suggesting you are simply making things up.
You have provided no evidence that Pc West was seconded to Special Branch at the time, and you have not suggested this before (as far as I am aware).
You are being vague about the police saying their own clock(s) were inaccurate to promote Jeremy Bamber's guilt - are you referring to evidence disclosed before Jeremy's trial, evidence given at Jeremy's trial, evidence disclosed later, or evidence that allegedly exists, but hasn't been officially disclosed yet?
