Thanks for that .
So as not that powerful it would not have any kick back as such . I guess I sort of assumed that her hand/arm would fall back and the gun could roll off her body . So I would be less surprised if it had been found just in fallen to one side if you see what I mean.
To be fair, at first police didn't know that she wasn't lying down when she was shot. If you are completely flat and have the gun across your body and pull the trigger is it possible it will stay on your body though it is also possible it can slide off, especially the stock.
Once they appreciated the blood proved that she was seated when she was shot that is what makes it apparent the gun was staged. Also gravity would have resulted in GSR landing on the gown had she been shot lying down so that is another sign it didn't happen. Then there is the moderator which further dashes any chance of that.
Leaving her body seated and the gun bewteen her legs would have been a smarter thing to do because that would be more realisitic given she was shot seated but he didn't think about them being able to prove that. When you are staging something you need to alter it as little as possible. The more you alter the more inconsistencies you create.
