Somewhere earlier today, I saw that his situation was disgruntled employee.
Had a discussion yesterday with a long time neighbor-friend. She is now a middle school teacher, previously an RN.
I asked her directly if our youung people are screwed up. She answered Yes, without hesitation.
I mentioned "helicopter" parents, and she replied "Lawnmower" parents. IOW the parents remove all obstacles, risks, dangers, from their lives.
Maybe age 36 is not the same,but nevertheless a mass shooter, has wrong ideas about problem resolution in their lives.
I read about drugs, Aderall, Marijuana, Meth, heroin, oxy, fentanyl.
I listen to younger people at Alcoholics Anonymous. They seem indifferent to risks of drugs and drink. Almost all talk about their ADHD, their depression, their anxiety, etc.
Cops and paramedics carry Narcan. The entire system they live within, protects them from poor behavior.
There must be some situation in this shooters life, that he didn't like, so he used an entirely wrong metod of coping.
