After catching up here, I've noticed that not many posters want to try and understand the struggle this little boy faced everyday. He obviously has something going on that means his brain is wired differently and he needs a whole lot of help. He may have ADHD, he may have something else, or ADHD and another co-morbid condition, but he clearly doesn't see the world the way someone neurotypical does, and his perception of events do matter, the way he felt drove his actions, and just because we can logically sit here and say that AZ had a class of 30 kids that needed her attention, and she was probably busy with the class, a 6yr old doesn't see it that way, they don't understand that what they have to say, or what they need has to wait. 6yrs old is still so young, empathy and awareness of other people's needs isn't anywhere near developed enough for in the moment thinking, and for a neurodiverse child with poor emotional regulation, possibly at a much younger developmental stage than their actual age, with impulse control issues, it's even harder.
Obviously I'm not excusing bringing a gun to school and shooting his teacher, although I dont believe for a second he had any real concept of his actions in the long term, we are all looking at it through an adult lens, and he absolutely should have not been alone without 1:1 help in that classroom, but some of the words used to describe this little boy in this thread really are awful. He is just a little boy and he needs help and empathy, not labelled a psychopathic monster who needs locking up.
As an aside, I have also noticed that everyone has seemingly ignored one thing, one of the incidents described a lot in articles has been the smashing of the cell phone, which of course is wrong and not saying it isn't, and I'm not blaming AZ for what happened to her, or excusing the little boys actions at all, but nobody jus asked why AZ was on her phone in class? Why she told him to go and sit down when he was speaking to her and she continued to do something with her phone whilst he was asking for her attention?. Why does she even have a cell phone in the classroom? That's not allowed in my kids school, or the school that I worked in, not even switched off in a bag or pocket during school hours for safeguarding reasons.
Anyhow, if this is true of the phone breaking incident, I can see why the boy was frustrated and felt ignored, and for a child with emotional dysregulation and impulse control that can escalate in seconds. Again, not an excuse, but a reason, and then he was suspended for the incident, and now you have an angry and emotional little boy who only feels the injustice of his punishment, because in his mind he needed her attention and she dismissed him, that made him feel bad and he lashed out, but he can't explain how he felt, and why he lashed out, and he doesn't understand why he was the bad guy when he just wanted to talk to her, and so the escalation, the "revenge" came. He isn't emotionally mature enough to understand any of it.
A quick Google of levelling behaviour and rejection sensitive dysphoria may be helpful to understand what I mean.
AZ absolutely did not deserve what happened to her, niether did the other children in that class, or any of the other people that have been on the end of this little boys violence, they were all failed because this little boy was failed.
My post is about reasons, not excuses. I hope I've managed to convey that, it's hard to do so without it seeming to be on one side or the other.
