In both the Sandy Hook School shooting and the Colorado Movie Theater Massacre the one common denominator was that the gunman suffered from mental illness. Each of the killers (sorry not gonna use the tern "alleged shooters" even though the Colorado murderer is still on trial) had long escalating history histories of mental problems. Had these individuals, and other like them, been dealt with there would be less innocent victims in the world.
There was a time when someone with mental illness was simply locked away in an mental institution. To protect him/her from themselves and from hurting society. Nowadays we just hand them a bottle of pills and send them home with a hearty: "Good Luck!" It may be time to go back to putting those with real issues into a place where they can get the help they need. Look them away. Re-open the "Nut Houses" as modern technologically advanced hospitals staffed top notch medical staff professionals who can help people battling mental illness. It won't be easy but it's better than letting another school full of kids die.
What would I do if God forbid one of my kids developed mental illness? Would I lock them away in hope that modern medicine would help them? I honestly don't know and hope I'll never have to. I do know that I would not take that kid to a gun range and shoot off weapons with them (as the mother of the Sandy Hook gunman did.) The worst part of all these mass shootings is that the end result is usually a mentally ill unstable killer guns down a bunch of innocents before taking their own life. May I suggest to anyone out there who is thinking about hurting people that don't deserve it--get medical help. Or if you really want to do some damage skip killing innocents and cut right to the punch--Kill Yourself! The world would be better with out you and that's The Bitter Truth.
