We continue to perpetuate the myth that we can address underlying issues for all things. It is definitely worth addressing as many symptoms as holistically as possible, but the fact remains we don't have a cure for mental illness, stricter gun controls may have a limited impact in select cases (but we'll never know when it works), guards at schools "may" work sometimes, etc. I suspect the government will aggressively pursue improvements and should, but we'll still mourn losses to these type of hideous crimes in the future. The reality is a lot of the so called underlying issues that drive people to act this way are well beyond our control.
