12 Facts About Guns & Mass Shootings in the United States

~ a super Washington Post/Wonkblog article by Ezra Klein

When we first collected much of this data, it was after the Aurora, Colo. shootings, and the air was thick with calls to avoid “politicizing” the tragedy. That is code, essentially, for “don’t talk about reforming our gun control laws.”

Let’s be clear: That is a form of politicization. When political actors construct a political argument that threatens political consequences if other political actors pursue a certain political outcome, that is, almost by definition, a politicization of the issue. It’s just a form of politicization favoring those who prefer the status quo to stricter gun control laws.

Since then, there have been more horrible, high-profile shootings. Jovan Belcher, a linebacker for the Kansas City Chiefs, took his girlfriend’s life and then his own. In Oregon, Jacob Tyler Roberts entered a mall holding a semi-automatic rifle and yelling “I am the shooter.” And, in Connecticut, at least 27 are dead — including 18 children — after a man opened fire at Sandy Hook Elementary School.

If roads were collapsing all across the United States, killing dozens of drivers, we would surely see that as a moment to talk about what we could do to keep roads from collapsing. If terrorists were detonating bombs in port after port, you can be sure Congress would be working to upgrade the nation’s security measures. If a plague was ripping through communities, public-health officials would be working feverishly to contain it.

Only with gun violence do we respond to repeated tragedies by saying that mourning is acceptable but discussing how to prevent more tragedies is not. “Too soon,” howl supporters of loose gun laws. But as others have observed, talking about how to stop mass shootings in the aftermath of a string of mass shootings isn’t “too soon.” It’s much too late.

What follows here isn’t a policy agenda. It’s simply a set of facts — many of which complicate a search for easy answers — that should inform the discussion that we desperately need to have.

1. Shooting sprees are not rare in the United States.

Mother Jones has tracked and mapped every shooting spree in the last three decades. “Since 1982, there have been at least 61 mass murders carried out with firearms across the country, with the killings unfolding in 30 states from Massachusetts to Hawaii,” they found.

Can CT Scans Bump Up Your Cancer Risk?



Radiation doses from CT scans are often high and vary widely, and excessively high doses may contribute substantially to future cancers, a study shows.

CT scans are noninvasive medical tests that combine special X-ray equipment and computers to produce detailed cross sectional images of the body. The number of CT scans performed has exploded over the last three decades, growing from about 3 million yearly in 1980 to about 70 million in 2007.

The new study is published in the Archives of Internal Medicine. Study researcher Rebecca Smith-Bindman, MD, of the University of California San Francisco, says the idea for the research began "when I was looking at some individual scans; I was surprised at how high the radiation dose was. I thought it was time to start looking."

The new research comes in the wake of the discovery earlier this year that more than 200 stroke patients at Cedars-Sinai Medical Center in Los Angeles had received more than eight times the necessary radiation dose when undergoing CT scans. That, in turn, prompted the FDA to encourage CT facility personnel to review their protocols and be sure the values displayed on the control panel jibe with doses normally associated with the scan being performed.
