The real problem in this country we need to take of is mental health. The staggering percentage of youth that are suffering from depression is the real pandemic of our time, but no one in the national government is taking it seriously. Until they do, expect incidents like this to continue no matter what kind of gun control legislation is passed. Common sense legislation could help (though our government often doesn't do a good job with common sense), but it will not eliminate this. Addressing the causes of the mass increase in depression is the big, and admittedly very difficult step that will stem the tide.
