Mass Shootings, Private and Public

Gun Facts Posted on by

Even sullied terms can be analyzed. We came across a quality study that looks at “mass [not-just-public] shootings” and paints a not-quite-alarming story. Main Take-aways As defined more broadly herein: Mass shootings are not steadily increasing and are decreasing as a function of population. Most mass shootings are in private residences and are “family related.” Assault weapons are a minority share of guns used. A third of assailants had mental health issues, higher than the general population but lower than mass public Public and non-public The term “mass public shooting” has had a multi-decade, criminology-derived definition (4+ dead, not including the perp, in a single public place). These events, tragic as they are, are very rare; and in terms of dead people, they account for a fraction of a fraction of gun homicides each year. This fact has proved so inconvenient to some activist groups (including some activist media) that … Continue reading →

California Con

Gun Facts Posted on by

There must be an election coming. The current California governor is making presidential maneuvers and the New York Times appears to be propping up his (inaccurate) statements about guns. I lived in that politician’s home turf for 22 years, during his political rise, so I have a deeper than average interest – and knowledge – of what the reality is, and in which alternate reality the politician resides. Main Take-aways California’s gun homicide rate is exactly the national average. Their overall suicide rate is rising, but is 29% lower that national averages, which bends the curve on gun suicide rates. For mass public shootings, California has 17% more incidents and 60% more deaths than the national average. The New York Times agitprop In a rather choice bit of partisan hackery, the New York Times (NYT) makes the following assertions about California and guns.

Trends in Mass Public Shootings

Gun Facts Posted on by

The largest multilingual international database of mass public shootings (MPS) tells us that they are increasing globally, less rapidly in the United States, but the average number of deaths in American MPSs is rising faster than the world at large. Let us then look at some of the factors that may contribute to mass shootings and see if there are rising rates of underlying causes. Main Take-aways 41% of mass public shooters with mental health issues got their guns legally, and the rate is rising. MPSs are on the rise, but not steeply. Handguns are outpacing all other weapon types, including “assault weapons.” Higher capacity magazines are radically increasing in use. The rate of legally acquired guns is rising much faster than illegally obtained guns. Precautions and Notes Repeat after me… mass public shootings are statistically rare events, and as such, trends and isolating causes are of a fragile nature.

Mental Mass Contrast

Gun Facts Posted on by

It is well established that most mass public shooters (MPS) have mental health problems. The question is whether they are more prone to instability than the public and by how much. The answer is upwards of nine times as unstable. Major Take-aways Depending on the subtopic, MPSs are 1.4 to 9.0 times more likely to have mental health problems. Most commonly, they have “thought disorders” – a characteristic of psychotic mental illness – at nine times the rate of the general public. The Violence Project and Their Book We have discussed the Violence Project and mental health before. They study MPS due to significant funding (for which we are green with jealously) and unprecedented access to uncommon data. They have produced the most comprehensive database on MPS available. The Gun Facts project will continue to maintain our mass public shooting database because we track important variables that the Violence Project … Continue reading →

Mass Global Mix-up

Gun Facts Posted on by

“Mass public shootings are rising faster around the world than in the United States!” “Mass public shootings are rising faster in the United States than the rest of the world!” Stuff like this makes me dislike Twitter even more than I normally do. That I saw these contradictory statements, each citing “real data,” within 60 seconds of one another was my first clue that the pro- and anti-gun camps were shouting past one another and that somebody was not paying attention. Why the division? It comes down to definitions and data sources. The Data Disagreement Two academics – John Lott and Adam Lankford – have published papers that calculate the number of mass public shootings (MPSs) around the globe. These papers come to different conclusions and have caused one of these two to abandon the normal congenial language normally bandied by studied men and women. Geek smarminess aside, we see … Continue reading →

Mental Breakdown

Gun Facts Posted on by

“You gotta be crazy to shoot a bunch of strangers dead!” Yes. Crazy and untreated. A deeper dig into the mass public shooting (MPS) database with the most detailed mental health insights reveals that the American mental health system is ailing. High Level Takeaways 68% of MPS perpetrators have mental illness. Of those, 65% of them never received treatment. Of perpetrators who were previously suicidal, only half received treatment. Mood disorder medications have an outsized influence. The Violence Project Database A product of government funding and greater access to medical records, the Violence Project database of MPS has the most complete accounting of the mental health status of MPS perpetrators. Their database starts in 1966 with the legendary University of Texas tower shooting and goes on through early 2020. They also have nearly complete records of the perp’s mental health history, including rarified data such as the perp’s suicidality, their … Continue reading →

What leads To Mass Public Shootings?

Gun Facts Posted on by

That is the big question everyone is asking. You, I, even your crazy Uncle Jim who never “got over ‘Nam” don’t shoot-up elementary schools or their company headquarters. That leaves us to wonder what makes mass public shooters different that the rest? What causes them to disconnect from reality and society to the point where mass murder seems like a good idea to them? Well, we now may have some numbers to (partially) answer the question.

Assault Weapon Deadliness

Gun Facts Posted on by

“Assault weapons must be banned because they are vastly more deadly!” (It is equally believable that this was said by Everytown, MSNBC, or the crazy homeless person on the corner… it is getting hard to tell the difference.) Are “assault weapons” inherently more dangerous that any other type of gun? I know ardent gunnies will go into deep discourse about the relative energy transfer potentials of sundry ammo types and rifle configurations. But thanks to the Gun Facts Mass Public Shooting database, we can make a quicker review. The High-Level Numbers NOTE #1: “Assault weapon” is a legislative term, not a technical one. There are a plethora of “assault weapons” laws that cover everything from handguns to hunting rifles to Lord Knows What. So we use the 1994 Federal Assault Weapons bill definition since it is the only one that covered all of the United States. NOTE #2: It is … Continue reading →

Fame, Media and Mass Shootings

Gun Facts Posted on by

Why people shoot herds of innocent bystanders in bars, concerts, movie theaters and schools is an area of earnest interest to the Gun Facts project, and to other researchers. So acute  is this interest that the academic journal Criminology & Public Policy devoted their entire February issue to 16 new papers on the topic. The Gun Facts project hopes to read all of them, but we start with a tantalizing and slightly flawed item, Why have public mass shootings become more deadly? Assessing how perpetrators’ motives and methods have changed over time. Not criminology malpractice This certainly is not a John Hopkins style selection of anti-intellectual tripe composed (allegedly) by doctors pretending to be number nuts. No, this paper is rightful criminology research and the type that the Gun Facts project prefers – namely being devoid of statistical hocus pocus and instead a solid tally of bad tidings. In short, … Continue reading →

Magazine Capacity Muckraking

Gun Facts Posted on by

The capacity of a firearm magazine should not make anyone high. But given the hyperbole over “high capacity” magazines, I fear some politicians are positively stoned. Whenever there is a mad rush to legislation, accompanied by exaggerated sound bites, we at the Gun Facts project just have to take a closer look. Research is our drug of choice. Main Take-aways Magazine capacity is only applicable to mass shootings Mass shootings are rare events Magazine capacity is not the underlying factor in high death rates The number of people killed at mass shootings is a tiny fraction of homicides Legislative Limberness Exactly what is a “high” capacity magazine? It depends on who you ask. Ardent firearm enthusiasts consider a 30 round magazine commonplace and can cite meaningful usefulness for 100 round mags. Some gun control supporters believe anything over six is excessive. As with “assault weapons”, “high” capacity is in the … Continue reading →
