No one may read this rambling treatise, but my thoughts after lurking a bit in the thread.
I wish it shocked me that no one seems to be looking at a truly objective, fair, implementable and potentially successful solution in a comprehensive sense. The NRA blames everything except current gun laws and the right to carry. Others get aghast at the thought of teachers being armed. It seems you are on one side or the other, when most everyone (except probably the NRA) has SOMEthing to bring into the conversation.
I'll say this - the tragedy in Sandy Hook has me REALLY thinking gun policy for the first time. As a firm believer in the rights of the individual, I think the right to arm yourself is essential, and not within the Constitution for no reason.
However, it's apparent that the right of innocent people to not be killed by folks with guns (or go ahead and say it, killed by guns, because except in very rare instances, a knife will usually wound, and certainly wont mass execute regardless of who is carrying it) far outweighs the right for someone to carry at this point.
To me, its becoming clear that IF we don't find some meaningful solutions to gun violence, then it's not those who want more gun restrictions that should be concerned long term about policy, but gun owners and gun ownership rights' defenders. Because eventually you just say screw it, no more guns. And I think that is potentially dangerous on a whole bunch of levels - which is another discussion as to why.
Basically, we must look at ALL the options out there, extreme and otherwise, and find the right mix of all. We have to treat the effect, the shootings, because they acutely kill people and harm communities, and other solutions will have a lag before effectiveness, so we have to do something now. Is that cops in schools? Arming teachers? Getting certain especially deadly weapons such as assault rifles off the streets now?
However, as many note, without addressing a number of underlying issues, many that we really don't fully understand even (i.e. how much do video games contribute? at all? a lot? why is this usually a middle class or upper middle class white epidemic. not always, but mostly). So, we need to address the CAUSES of these actions, as best we can, understanding sometimes people are evil, or go crazy. But there must be a way to help some, address the issue to a better degree than now, and also perhaps have more advance warning with behavioral signs and evidence before something terrible occurs. Mental Illness and how our nation seems to fail so many individuals and families in addressing it.
It's almost as if we need to list the full range of solutions, and try to, without bias, find what will work - short and then long term.
My thoughts:
Arming Teachers - I don't see the problem. Does not have to be mandatory, or perhaps school security now has to essentially pass enough tests to become armed. While the Israel issue isn't perfectly clear, I have learned first hand that in crowded places, when you see the good guys, and many of them much like you, with arms, you do feel and are safer. Perhaps it's optional, or some group of teachers gets training and certified. Don't see the harm here.
Cops in Schools - As noted just above, what about just school security? Just too costly as noted above, and do we want cops to have to patrol our schools now? But it can't just be dismissed as it addresses the acute fear of something happening short term.
More stringent gun legislation or gun bans - It would seem to me that a reasonable compromise here is to get the most dangerous weapons off the street totally. Those which can achieve mass destruction and have nothing to do with gaming and really are meant as weapons of war in the most extreme of circumstance. But, for practical and philosophical reasons, we are not going the England route. No way we are taking all guns away, so what is the balance and how do we best make sure that (1) the right guns are there and available to provide for gaming and personal security and (2) most importantly, how can we make sure that the only people who have access to guns are responsible with them, are well trained, must demonstrate competency in use and safety precautions to maintain ownership, etc. Need some monitoring here, and while I'd prefer not to have to give my info up to some gov't agency, the reality is we have to because people's liberty and safety is at risk here at this point, so the current system just isnt enough.
Address the root causes of such violence - This is huge here. Because it's not about limiting one person freedom or anothers by allowing guns and having innocents killed or not allowing guns in the first place. Is it mental illness? Violent male culture and video games? What are the roots, because we need to be more honest about them and work through it.
Some other suggestions out there, but I do believe only a real mix and match of ideas from the left, the right, gun owners, gun haters, all of us must have some input into this for a solution to take hold.
For me, I'd love to keep the gov't out of it and allow more personal freedom for guns, or whatever - however history and recent history is demonstrating that the system is completely broken. Thousands and thousands of lives are lost every year to this and we must really find a better way.
For me, the suggestion is allow more private carry of guns (i.e. teachers, certified civilians etc) restrict significantly, access to guns only to someone who can demonstrate they are responsible, trained, etc via certification, with harsh penalties for anything illegal - and we must, absolutely must address how our nation (mis)treats mental illness, those who suffer from it and those who are harmed by those who need medical help, but do not receive it / are supported enough, if at all.
