I've fired one (bolt action) years ago and I can't remember any recoil at all from a .22.
Working the bolt alone to load a new round into the chamber results in movement of the weapon unless quite skilled and takes additional time that is not needed with a semi-auto. That is why Jerey wanted a semi-auto to commit the murders with.
Sheila had numerous things working against her in terms of dexterity ranging from her natural problems to ones caused by her medication and that would have resulted from rapid movement in a crazy rage. More significantly she never fired the weapon before which alone would result in a learning curve. That is if she figured out how to use it. There is nothing to suggest she would be able to figure out she needed to chamber a round manually or how before she could be disarmed.
For Jeremy to be innocent there had to be a whole long series of unlikely events that occurred and some that are not even possible.
That is why Jeremy supporters want to address each independently because if you try arguing 30 extremely unlikely things all occurred in succession you look like a fool. In the meantime they also ignore many of the most daning things because they have no real way to refute them.
Then they whine and say he should be released though they failed miserably at presenting any evidence that refutes the evidence that convicted him and thus have not in the least demonstrateed he is innocent and should be released.
Deciding they will ignore reality and pretend Sheial would not have gotten GSR and blood on her clothing or alternatively pretend that she changed and that the GSR/blood stained clothing was hidden at WHF but never found by anyone though everything was gone through amounts to denial simply not proof or evidence.
Deciding to pretend she did not suffer from a contact wound as the experts assert and was not shot with the moderator on the gun but rather that the parents were shot with the moderator at contact range and somehow Nevill's less stable AK1 survived while June's AK2-1 did not and somehow in some mysterious manner the blood failed to intimately mix though there is no explanation as to how that could have occurred amounts to denial. It is further denial to believe Sheila went into a crazy rage, found the gun in the kitchen where Jeremy left it then decided to go to the close to get the moderator to place on it, used it with the moderator attached, removed the moderator after killing everyone then put it away in the closet to hide it so no one would know it was used. Why would she get it out let alone put it away to conceal its use? Also live in denial by pretending that Sheila would use 20 rounds from the batch of bullets he left in the kitchen but then go to the closet to get 5 more instead of continuing to use the kitchen supply even though 30 remained in that supply.
There is nothing to suggest these things are credibile, People just decide they want to beleive Jeremy is innocent no matter what and are willing to ignore anything and everything against him for no rational reason but instead for the biased reaosn they don't want to face his guilt.
In fact they are so biased they even revise Jerey's claims and statements. They know what Jeremy said was harful to his position so they make up different testimony for him or ignore his testimony. Alias et al spent many days insisting that even though Jeremy himself admitted he climbed through the kitchen window that a human can't fit and thus Jeremy was just lying about being able to do so. Why would he lie to admit something unfavorable to his position? You lie to say something favorable to your position.
The thing about living in denial is that living in denial only impacts your own personal views. It doesn't provide any basis upon which to argue from.
When arguing before a court or even just informally saying you refuse to face that Sheila's fatal wound was a contact wound and thus can't have resulted in drawback into the weapon doesn't cut the mustard. You need strong evidence that proves the experts who asserted it was a contact wound were wrong. Choosing to believe that because it is necessary for Jeremy to be innocent and you want to believe Jeremy is innocent amounts to blind faith simply.
That is where we find ourselves today.
We have on one side those who have blind faith in Jeremy who live in denial as a result and then those who don't and who thus face the evidence against Jeremy and consequently believe he is guilty.
That is why there is a stalemate. Adam thinks he can convince such people to abandon their blind faither not understanding they intentionally have decided to reject and and all evidence against Jeremy no matter what and instead to have blind faith.
There are some unscrupulous Jeremy supporters who don't want to admit they are operating on blind faith so they distort and pretend that there is evidence to establish someone was inside alive while police were at the scene, that Nevill had phoned police, that blood was planted in the moderator and things of that sort though they in fact have no evidence at all to establish such occurred.
If such unscrupulous posts stopped popping up and Adam stopped trying to waste his time convincing them to give up their blind faih the site would largely come to a halt. Most posts are either a reaction tot he distortions posted by Jeremy supporters or reactions by supporters to Adams posts.
So it is just a vicious circle with no progress being made.
