Blame the parents for not teaching their child guns are not something they can ever touch, for not having a gun safe ( love my fingerprint safe. No extra time to access and no ability for kids to get into it), for not even noticing a six year Old's back pack had that extra weight. I mean I hand my kids their backpacks every morning as they head out the door.
I feel terrible for the teacher, the students who witnessed this, the families whose lives are forever changed. I also feel TERRIBLE for this CHILD. He will forever live with seeing the consequence he didn't understand. He will forever live with the guilt. And even if he is a psychopath who never values human life, he is young enough and malleable and could be redirected (again not something a 6 year old fully comprehends or would even consider when using a firearm)
Put a 6 year old in prison, much less adult prison, you all but guarantee he ends up a hardened criminal
Think it through man!
