I'm not saying any of the above is incorrect; however, do you have anything to corroborate your claims in relation to statistics?
I will see if I can find any sources that are free and available online most studies are in journals which you need to pay to access.
There are different stastistics for handguns than rifles. I gave them for rifles but might end up having to find one that doesn't distinguish between handguns and long guns.
If I break down the stats for women then it will be even smaller because not as many women use guns to commit suicide as men and far more men than women engage in murder suicide. Most murder suicides women engage in are to kill spouses and or kids not parents.
The problem with stats like this is there often is an exception to a rule or first time for everything no matter how rare so ALONE the stats are not meaningful, they only are meaningful as part of the overall picture.
Something can be extremely unlikely and yet their might be undeniable evidence something extremely unlikely has happened.
I simply don't see that here.
Many people suggest that the mental health picture of Sheila means she did it and that the evidence that proves she didn't must have been planted or faked. Everything about the mental health picture and nature of the event suggests it is unlikely she did it.
The evidence need to overcome that is to look in detail for forensic evidence that evidences such. I think many peopel don't want to look at such evidence and want to dismiss it because it is damning to Jeremy so overstate the mental health aspect instead.
From a legal perspective that forensic evidence is the star of a case and that is even more true with relation to appeals so most efforts should be devoted there.
