Excerpt:

Mass shootings are no more common than they have been in past decades, despite the impression given by the media.

In fact, the high point for mass killings in the U.S. was 1929, according to criminologist Grant Duwe of the Minnesota Department of Corrections.

Incidents of mass murder in the U.S. declined from 42 in the 1990s to 26 in the first decade of this century.

The chances of being killed in a mass shooting are about what they are for being struck by lightning.

Until the Newtown horror, the three worst K–12 school shootings ever had taken place in either Britain or Germany.

[…]First, the mental-health issue. A lengthy study by Mother Jones magazine found that at least 38 of the 61 mass shooters in the past three decades “displayed signs of mental health problems prior to the killings.”New York Times columnist David Brooks and Cornell Law School professor William Jacobson have both suggested that the ACLU-inspired laws that make it so difficult to intervene and identify potentially dangerous people should be loosened. “Will we address mental-health and educational-privacy laws, which instill fear of legal liability for reporting potentially violent mentally ill people to law enforcement?” asks Professor Jacobson. “I doubt it.”

[…]Economists John Lott and William Landes conducted a groundbreaking study in 1999, and found that a common theme of mass shootings is that they occur in places where guns are banned and killers know everyone will be unarmed, such as shopping malls and schools.

I spoke with Lott after the Newtown shooting, and he confirmed that nothing has changed to alter his findings. He noted that the Aurora shooter, who killed twelve people earlier this year, had a choice of seven movie theaters that were showing the Batman movie he was obsessed with. All were within a 20-minute drive of his home. The Cinemark Theater the killer ultimately chose wasn’t the closest, but it was the only one that posted signs saying it banned concealed handguns carried by law-abiding individuals. All of the other theaters allowed the approximately 4 percent of Colorado adults who have a concealed-handgun permit to enter with their weapons.

[…]Lott offers a final damning statistic: “With just one single exception, the attack on congresswoman Gabrielle Giffords in Tucson in 2011, every public shooting since at least 1950 in the U.S. in which more than three people have been killed has taken place where citizens are not allowed to carry guns.”

There is no evidence that private holders of concealed-carry permits (which are either easy to obtain or not even required in more than 40 states) are any more irresponsible with firearms than the police. According to a 2005 to 2007 study by researchers at the University of Wisconsin and Bowling Green State University, police nationwide were convicted of firearms violations at least at a 0.002 percent annual rate. That’s about the same rate as holders of carry permits in the states with “shall issue” laws.

Please read it. It’s good to have the facts when deciding what to make of individual tragic occurrences.
