Instead of concentrating on trying to keep guns out of the hands of mentally ill people who roam among us untreated, we could try and do something about better treatment for the mentally ill.
we could, and probably should. I like to suggest doing something else, as well. Something a little..less enlightened in some people's view. Something we used to do, and seldom do today.
Making certain that those who shoot people for fun or profit never, ever be physically capable of doing it again. Crazy or not, I don't care. If they did it, there should be permanent consequences.
I think we spend too much time pretending we can understand the motivation and that understanding it will prevent criminal behavior.
We understood the motivation of the Kamikazes, but what stopped them (when it did) was AA fire and CAP. In other words, force. Bombing the planes on the ground helped too. Again, force. On the other hand, its really a not a completely fair comparison, as enemy soldiers kind of have openly declared their intentions in war by being "the enemy".
We live in a society where we are taught that despite appearances, no one is a criminal until they commit a criminal act. TO my way of thinking, Red Flag laws ignore that.
