Why gun safety and training at a early age is paramount. Understanding the ramifications and permanent damage done by not handling firearms in a proper manner is key to making sure accidents and misguided behavior doesn't happen.
Why would a 6 yr old think of shooting a teacher well that is the question what would prompt a child of 6yrs old to feel so traumatized/Victimized that he would steal a firearm and use it on a teacher in what clearly appears to be an act of perceived self defense.
Maybe this child has a history of mental illness and has showed actual signs of psychopathic tendencies some children do as young as 2/4 years of age. But if that was the case then why did he stop at just shooting at the teacher? Why did he target her first? LEO first said there at been a altercation between him and the teacher and then later reworded that to a interaction between them on a earlier occasion, was there a pattern? Was this documented?
It appears there is a history here and what that is needs to be determined. But hey let's just focus on the gun as apposed to the actual incident and the reasons that set it into motion.
