"100% of gun massacres occur by people with mental illness. If you disagree with that statement, be prepared to make the case that there are some rational, cool-headed people who, after thinking clearly and weighing the pros and cons, decide to commit mass killings. There aren't. Rather than focusing our efforts on demonizing society, guns, gender or family, we should focus our efforts on getting people with mental illness the help they need. The fact that there's stigma associated with receiving mental health care is a problem. If you know someone in need, reach out and try to get them help. Trying to rationalize an irrational act is futile. Rational people don't go on shooting rampages." -Maddox
This is about as real as true as it gets, but calling for societal changes, and these changes actually happening, are not the same thing. James Alan Fox, pretty much the world's foremost authority on mass murder, believes that you cannot spot or prevent it, since these killers for the most part lead ordinary lives. You can, however, spot them because they obviously stockpile weapons and ammo in preparation for bad things that are going through their head. Before you cast judgement on some nutcase who went around murdering people, ask yourself if anyone was there to support them in their time of need, and that answer will almost always be no. Then ask yourself if you have ever gone out of your way to lend support to someone, and if that answer is no, you have not done your part to stop mass murder.
