The profile of this kid is almost cliche. He has worked most of his life and always succeeded. He has worked up to the PhD level and only then tasted failure for the first time when he couldn't find a job.
I tasted a bit of that myself when I finished my Masters degree and ended up as a stocker at Walmart because there was nothing open in my field. With no prospects in the near future and an ever impending feeling of failure as I collected food stamps and relied on family and friends I could feel my own mental health lapsing. Having to take my orders from a supervisor with an Associates degree was more than a little humbling.
It doesn't surprise me that there are people out there who would snap. The prospect of having to be something less than perfect after all that effort and work and expense. I'm surprised there haven't been more attacks like these in the recent months.
Neither side in an argument can find the truth when both make an absolute claim on it.
Couple in Colo. Theater Shooting Escape With Baby and Toddler in Tow - ABC News
He had the baby, but the baby cried and he was afraid "he" meaning the man, would get shot so he put the baby down and left him, the little girl and his fiance there and got out. He actually got in his truck and was driving away! She called him and then he went back and got them and they went to the hospital.
I read this online and I think it's spot on:
"The proliferation of guns, the lack of access to mental health services, a pervasive sense of isolation, glorification of violence in our society all create conditions that lead to such tragedies."
All the rest is meaningless and there is the answer
It's truly unfortunate that you live in an area with so many irresponsible gun owners. I would move.
