Anyone pretending to be more brain dead than I am, forget about it, your only fooling yourselves, because if the shooter had been right handed, and for the benefit of those who are pretending not to understand what I am talking about, look at the images I have just posted - a right handed shooter would not get the bloodstained straition impact markings on that unique part of their lower right arm ' right wrist, unless of course, they were left handed, or even if they were right handed but handled the rifle with the fingers of their left hand at the trigger, and their right hand supporting and directing the barrel of the gun at victims that they were shooting at...
Any such shooter, who was using the fingers of their left hand at the trigger, and their right hand supporting and directing the barrel of the gun at a target, would without doubt be at risk of the lower part of their right arm / right wrist being struck by each and every spent brass cartridge casing ( bloodstained or otherwise) that was being ejected in correspondence to each of the 23 shots fired by the shooter at any prospective victim - The 'bloodstained impact markings' which are present 'upon the lower part of Sheila Caffells 'extended' lower right arm' and 'the part of her right wrist' are consistent with 'having been the shooter', that part of her anatomy being 'so unique' that such markings could 'not possibly have existed' by 'any other legetimate means'...
