Why is it most liberals seem to focus on gun control, and gloss over better mental health treatment, as the most effective solution to this problem? They seem to hardly even mention it.
Because nobody - literally nobody - knows what that would even mean.
Making sure people have access to affordable, efficient psychiatric care is part of the puzzle, but it's a small part. I don't know why it's suddenly been christened the silver bullet in massacre prevention, and as you said, nobody can seem to outline specifics beyond "make mental health services better!"
We're doing ourselves a disservice by thinking these killings are only perpetrated by generically and predictably insane people.
