Police had to arrange for the bullet (PV/20) which was fragmented, to be swapped over and replaced by a different whole control bullet which must have been test fired via the anshulz rifle, so that they could keep this a one gun crime, and conceal the truth about how Sheila was shot twice, once downstairs, and secondly, upstairs?
You do not tamper with a crime scene bullet unless you have got something to hide...
Ask yourselves this question - do you think or believe that someone swapped over the original fragmented bullet (PV/20) for a substituted whole control bullet for the purpose of making it a one gun matter relating to both shots inflicted to Sheila's neck / throat?
Yes, or no?
If no, how do you account for the transformation of a fragmented bullet as of 7th August 1985, miraculously becoming transformed into a whole bullet that the ballistic expert, Malcolm Fletcher, was able to positively link as having been fired via the anshulz rifle, along with bullet PV19?
