> Then another tortured soul shoots up a fast food restaurant. A mall. A kindergarten classroom. There are crazy people in every country on earth, many (most) of which have worse "health care" systems than the US; yet only in the US do kids shoot other kids with automatic weapons. I very much doubt it has anything to do with mental health (nowhere else in the world are young children medicated for being kids to such…
In a comment above, where I discuss the policy of the states in Australia, I suggested googling 'bendigo mental health'. If you do that you will see a degree of specialisation that far exceeds your presumptive normalcy.
Events such as these do appear to occur in clusters, and this leads to complicated questions. And of course it has to do with mental health, unless you honestly believe that such acts can be carried out by well balanced, psychologically stable individuals.
Inurement by familiarity I would agree is a factor, but it cuts both ways. There was a mass killing in Australia which followed only one month after a mass killing event in the UK, where I live. Isolated individuals also require social connections, and the strange self esteem accessible through active association with like minded others, even if unknown personally to them, seems to play a part. It's never a wise move to allow mentally damaged people to join a nervous uprising against the incumbent ideology, that often is seen as part of the reason for their repressed state. Though it might seem tortured logic on these actors parts, I think one of the reasons these shooting incidents are somewhat peculiar to the United States is because these actors see it as a right to bear arms against their oppressors.
On the other hand, the response of the rest of society is critical to developing ways to resolving ways to avoid these events. Either you exert enough pressure to put the uprisings back in their box, to be modified by planned action in due course, or you eek them out into a system of redress that has the capacity to control.
Either way it is indeed a mental health issue from a public health perspective. And their right to bear arms is guaranteed in defence of their freedom, through logic that is strange and barely comprehensible to most of us.
