We live in a country with approximately 280,000,000 guns in the possession of its citizens. At any place or time, one can lose self-control and start shooting.
Still, psychologists can say a few things with certainly about who is more likely to commit the most serious of crimes. Over 90 percent of killers are male, and the same holds for mass murderers—“I can’t think of a single case where a woman has done this,” says Schlesinger—partly because men tend to have more access to guns, which are usually the weapons of choice. The killers are usually somewhere between the ages of 25 and 35. They generally do not have previous histories of breaking the law in any serious way, says Levin. And they are not, on the whole, psychopaths, although they are often identified in the media as such. “A psychopath is someone with little conscience, little interpersonal bonding, someone who’s smooth and manipulative," says Schlesinger. "That personality has nothing, zero, to do with mass murder."

So, why should any American be afraid of Bush's 'terraists' when we're surrounded by other potential killers?
