While I obviously agree that safe gun storage is a major issue here (including figuring out whether it was locked up or not), I think the focus by the defense on how the dad is the one who bought the gun is not going to successfully shift all of the blame off of her shoulders. I am a mom. If my husband went out and bought my child a gun and I was at ALL concerned about their mental health, the very LEAST I would do is make sure it was always secured and only available with parental supervision. That isn’t just the responsibility of one parent. It is a responsibility of both adults in the home. I know nothing about guns but I most definitely know that my husband’s weapons that are in my home are behind locked doors and not accessible to my children.
I think her biggest failure, and the thing she will have a hard time defending, is what she did and didn’t do the day of the shooting when they were called to the school. EVEN IF she only knew what was on that worksheet, she knew he had a gun at home and he was clearly struggling based solely on what he wrote on that paper. I don’t for one minute think she expected this to happen but I also think there were many missed opportunities to just get this kid someone to talk to. If my child was texting me about demons in the house, I would never have let that just go. All IMO, obviously.
