Thank you for this insight. Very revealing.
I have an acquaintance whose son was a troubled kid and I saw her family go through hell trying to get services for him. They were an educated, employed, rather well-off family...and were devastated emotionally and financially in efforts to get the kid help. There is NOT ENOUGH HELP.
Not saying that is the case here as the family didn't even remove guns after the FBI came knocking. I don't know if they sought help or not, but they sure didn't take responsibility of safety and I expect charges to be made. The parents put the community at risk and they knew it and apparently didn't care.
