What a load of bollocks...provide some evidence or give it up! 
The evidence is there for all to see - gun at bedroom window by 7.15am, how did it end up on top of Sheila's body in time for PC Bird to photography it there from 10 O'clock onwards? No other gun was found resting up against any of the upstairs windows, non was photographed at any other upstairs window, no rifle was ever seized or made an exhibit in the investigations, so the rifle in question which WPC Julia Jeapes said she saw, can only have been the anshuzt rifle. Facts like this cannot be ignored. Who moved the rifle from the bedroom window after 7.15am, onto Sheila's body?
It wasn't J, he could not have done that...
Sheila didn't do it either because she was mistakenly pronounced as being dead downstairs in the kitchen. Cops knew she had been shot downstairs when they stepped into the kitchen. The anshuzt rifle was still resting against the bedroom window upstairs at 'that' stage, so cops could hgardly have shot her using that rifle now could they? So, work it out for yourself, they shot her with a cop gun downstairs, whilst the anshuzt rifle was still resting against the bedroom window upstairs. Nothing could be any clearer, the cop account about misidentifying dads body for a female is nothing but a red herrin', the mistake only applied to one dead body, not the two that were reported 'after' cops had entered the kitchen. If you don't know it, or if for some shady reason you choose to ignore the truth, I shall remind you by gleefully ramming the facts down your throat - cops reported a female body downstairs in the kitchen, after dads body had already been mentioned. Not once, but twice...
Get your facts right, before you open your gob...
