But we're not talking about firearms per se are we? We're talking about cartridge ejection patterns, blood at SoC and trajectories.
I don't need to test fire an Anshutz to know I ejects to the right. I can see with my own two eyes the weapon and have seen videos of the shells being ejected. I know base don such that the shells are not ejected to the left.
I know the experts FROM THIS CASE assessed the shooter could only have stood in the shaded area and could only have aimed the weapon in the direction of the bed. The gun had to be aimed with the victim in bed or next to the bed.
You disregard such and just keep making up it is possible for the shooter to have been shooting into the hall. You want to pretend Nevill was sideways on the stairs being shot at though the gun was aimed inside the room and it would make no sense to be sideways on the stairs.
There is good reason the defense didn't try raising any such claims- it is nonsense.
Make up the victims were anywhere next to the bed you want trying to explain where the shooter stood and the victim was by the bed or in the bed. That is the most one can do. The killer was shooting at people in/on the bed or next to the bed with the exception of the shot fired when June was in the doorway.
