Even the most ardent of guns rights supporters will admit that guns should not be in the hands of psychopathic killers bent on destruction and the slaughter of innocent people, after embracing evil in their heart, beyond any normal pale of right and wrong.
The question then remains, as it did after Columbine, Virginia Tech, and other shootings: what can society do to prevent such catastrophic events?
Unfortunately, there is not much that government can do: there are thousands of ways to implement violence, once one forms an evil intent. And with the Internet, any form of weaponry, chemical, bomb-making or lethal device, can be shipped and mailed to your door in days. All you need is a credit card.
I would just ask this of Hollywood and the media: stop the deadly gratuitous use of violence in films that glamorize violence as true power, that make violence into some sort of glorified cartoon, and the implication that there are no long-term consequences to its use.
Crazed, evil and unstable people cannot distinguish reality from fantasy, and have no moral compass. Your movies just blur the distinction further.
Then, it is up to you and me to step up face the killers down.
