I'll start by being clear that I think arming teachers is one of the worst ideas I've ever heard in my life. Outside of that though, I think it's going to take a little bit from every column. No one thing is going to be the solution. We need better gun control, but we're too far armed to think we can prevent everyone who might do this from getting their hands on a gun capable of doing it. So that's only part of the solution. We need MUCH better mental health care and prevention. But, again, we'll never be able to treat everyone who needs it, especially if they aren't open to treatment. So, that's only part of the solution. We need better protocol for limiting casualties once the shooting begins. I don't want our kids going to school in a prison. But, I do think we are going to have to make some uncomfortable concessions on this. Perhaps secure entrances with airport type security. Classroom doors that can be made impenetrable in an active shooter situation. Some of this will seem draconian, and it will be expensive. But, it's worth spending the money. We need better monitoring of obvious signs. Often times there aren't any. In this specific case, there were an almost a seemingly obscene amount of red flags. Law enforcement, students, parents, and school staff have to take threats and behavior more serious. Yes, it will lead to many times where it is much ado about nothing, they are kids after all, and kids say stupid things that they don't mean sometime. But when they say those things in combination with a horde of semi automatic weapons, something has to be done. I'm sure there are countless other avenues as well, but mainly I think it will have to be a little bit from every column.
