Nothing anyone says is evidence, or becomes evidence, until it is presented at court to support arguments made by one party or another - you can say all you want and you can say it as many times as you want, but there is more evidence to prove that the police tampered with the crime scene, and that they moved the bodies and planted the rifle on Sheila, and that they interfered with the crime scene ammunition, and everything else they are responsible for doing, than there is or ever could be, to show that JB killed anyone, or that he could have stage managed the scene, as alleged...
The evidence used to support the prosecution of JB is fundamentally flawed and the silencer / blood / paint evidence should not have been used to convict him...
