As for the incident in America, it's all the more tragic because it could've been so easily prevented.
That gun, if needed at all, should've been kept unloaded, safety on in a locked box /cabinet. Ammunition should never be kept near the gun.
The kid was removed once and then he returned. However what support and interventions were available to him during that time and after?
It sounds like he is required to have a 1 to 1, but without his mother he wasn't provided with one.
The numerous complaints and safeguarding issues raised during his school years. The lack of action.
The lack of action and intervention when several pupils AND staff raised concerns about a gun and stated they had seen one. It's fucking ridiculous. The people in charge should not only be fired, they should be charged for criminal negligence. So should the parents.
Now you have a teacher that was shot ,traumatised and significant injuries and medical bills. A teacher that might never return to a classroom.
A bunch of scared and traumatised 6 yos that had to be taken to safety because their classmate shot their teacher. At school.
A six year old that shot another person and now has to live with it and the aftermath.
