I go back to my thought that we will have to have an enormous shift in our American "ethos", if that is the correct word, our absolutism regarding "freedom". Land of the free. Home of the brave. All that shit.
1) Remove all the guns? Too late even if we tried. Can you imagine the "revolution" if the government came to everyone's door and started collecting guns? That horse is already out of the barn. I think it would be logistically impossible. If possible, it would take generations.
2) Stricter gun laws. We can't/don't enforce the one's we have now. Experience says laws don't do it. Do we put the seller in prison? A licensed seller who has passed all the tests and shown himself to be a good hobbyist? We have a drummer on this board who might take offense.
3) Keep guns out of the hands of crazy people. See my original post. It is difficult to impossible to 100% accurately diagnose a crazy person, and some crazy people come in and out of their illness. At what point do we say "Okay man, you've been psychotic three times and three's the limit. We gave you two chances, but no mas. Here's your straight jacket". Or, "Fuck man! We missed that one! He killed people on his first psychotic episode! Oops!". Crazy people are an invisible group, in most cases. If not invisible, at least very difficult to see. And if we see them with 100% accuracy, at what point do we take away their freedom? Where is that line? Who gets to determine that line? Who gets the responsibility for enforcing that line?
4) In the deep dark recesses of my past, I spent 5 years working at "mental asylums", or "looney bins", or the "nut hut", whatever. They are not as horrible as the horror movies would have you believe, especially with the advent of more refined antipsychotic medications. Not as bad as you think, but I sure as hell wouldn't want to live out my life in one. I sure as hell wouldn't want my precious family member to live out their life in one. I sure as hell wouldn't want to be the one who made the decision to sentence a fellow human being to live out their life in one. Even if we spent half the national economy making mental hospitals into "resorts", I wouldn't want to live my life out in one. "Sir, here is your room at the Hilton on Waikiki Beach. Your dinner will be served at 6PM. You will not be allowed to leave the premises. Ever."
As I said above, this will take an enormous change in the fundamental beliefs we have about society, about the worth, and the price of freedom. Is my freedom from the anxiety of worrying about mass murderers equivalent to the freedom of a mentally ill person? If we can make that decision, where do we draw the lines? The intricacies of such legislation would dwarf the tax codes in complexity. To quote the great philosophers Mick and Keef, "It's a Bitch".
