"There is a worrying trend in academic medicine which equates
statistics with science, and sophistication in quantitative procedure
with research excellence.
The corollary of this trend is a tendency to look for answers
to medical problems from people with expertise in mathematical manipulation
and information technology, rather than from people
with an understanding of disease and its causes.

"Epidemiology [is a] main culprit, because statistical malpractice typically occurs
when complex analytical techniques are combined with large data sets.
The mystique of mathematics blended with the bewildering intricacies
of big numbers makes a potent cocktail...."
- Bruce G. Charlton, M.D.
University of Newcastle upon Tyne, 1996

In February 2002, a Harvard School of Public Health study was published in the Journal of Trauma.(1) According to the Violence Policy Center's (VPC) interpretation of that study, "The elevated rate of violent death among children in high gun ownership states cannot be explained by differences in state levels of poverty, education, or urbanization."(2) [Emphasis added.]

The authors of the study did not put it quite so bluntly; they knew better. Yet, according to the abstract of the study, they asserted:

"A statistically significant association exists between gun availability and the rates of unintentional firearm deaths, homicides, and suicides. The elevated rates of suicide and homicide among children living in states with more guns is not entirely explained by a state's poverty, education, or urbanization and is driven by lethal firearm violence, not by lethal nonfirearm violence."(1) [Emphasis added.]

In the authors' abstract, the words "not entirely" become the key to understanding the preordained drift of their gun control agenda and the expected, result-oriented conclusions. The published study, indeed, is the typical, hackneyed public health, result-oriented gun research repeatedly published in the medical literature claiming that "gun availability is responsible for firearm violence."

Thus, perhaps, we should analyze further the meaning of the words "not entirely." What follows is a preliminary critique of the study while the primary, raw data is requested from the authors for further analysis.

According to the study, the five states with the highest gun ownership --- Louisiana, Alabama, Mississippi, Arkansas and West Virginia --- were more likely to have children dying from unintentional firearm injury (gun accidents), suicide (with or without firearms) and homicide than children in the five states with the lowest levels of gun ownership --- Hawaii, Massachusetts, Rhode Island, New Jersey and Delaware.

Why more western states like North and South Dakota, Iowa, Wisconsin, Utah, Nebraska, Alaska, etc., that have relatively "easy availability" have low firearm death rates for children is left unexplained.

In fact, the whole study revolves around using the phraseology "not entirely" to exclude the much more important reasons for violence with or without firearms: the levels of poverty and education, not to mention the related cultural factors and the utter breakdown of the family in those states by welfare and other government policies.(3)

Another point of contention is that, as usual, the public health researchers ignored the beneficial aspects of gun ownership and concentrated only in obtaining supporting evidence for their preordained conclusion that firearm availability is responsible for violence in our society. Thus, they seek to disarm the law-abiding citizens who benefit from gun ownership.

It is the law-abiding who obey the law, criminals do not. When the government passes restrictive gun laws, those laws interfere with a constitutional right as well as in the lives of law-abiding citizens. Yet, these increasingly draconian laws do not stop criminals (or the mentally deranged) bent on breaking the law - they are only further impositions on ordinary Americans.

Television and Media Violence and Juvenile Delinquency

Another observation virtually ignored by the authors of the study, as well as their promoters at the VPC, is the effect of television and media violence on juvenile delinquency.

In the summer of 2000, the media, including medical journalists, focused their attention on the associations of violence in television, music, video games and movies to violent behavior in children and adolescents.

To this end, a consensus statement of experts released on July 26 and sponsored by the AMA and other medical groups proclaimed, "At this time, well over 1000 studies --- including reports from the surgeon general's office, the National Institute of Mental Health and numerous studies conducted by leading figures within our medical and public health organizations --- point overwhelmingly to a causal connection between media violence and aggressive behavior in some children."

Moreover, the report continued, "Its effects are measurable and long-lasting...prolonged viewing of media violence can lead to emotional desensitization toward violence in real life."(4)

Why is all this background information being discussed about television violence and crime — virtually, life imitating art? Because, interestingly enough, the authors of the Journal of Trauma study ignored relevant and important data impacting directly on their research.

Let us look at Table 1.


Rather than using the biased, VPC shibboleths "highest" or "lowest gun ownership states," I have used the more objective terminology, "high" and "low levels of juvenile violence" states, for the purpose of this critique. As clearly shown in this table compiled from government statistics (1994), it turns out that, among other factors, students in the "high levels of juvenile violence" states not only watch more television (24.2 percent) than those in the "low levels of juvenile violence" states (19.8 percent) but also do "less reading on their own time almost every day (39.6 percent vs. 44.2 percent)."(5) No statistical analysis is necessary to show that students in the HJV states spent less time reading and more time watching television. This important variable was not even mentioned or discussed by the authors!

Incidentally, on February 28, 2002, I wrote Dr. Matthew Miller, the lead author of the Journal of Trauma study and requested that he kindly supply me with the primary, raw data which he and his associates used in reaching their conclusions.(6) He never did.

In Part II of this article, we will be looking at other factors that Miller et al claim were "not entirely" responsible for the high rates of violence in the mostly southern states.

America, guns and freedom – Part 2 in SNI today!

America, guns, and freedom – Part 2: An international perspective by Dr. Miguel A Faria Jr., President, Hacienda Publishing, is posted in the online, peer reviewed journal Surgical Neurology International (SNI) and is available from:

This two-part article explains not only why Americans have a fascination for firearms but also why the legal possession of firearms by civilians is associated with liberty, not only in America but in the context of the world historical perspective. The article becomes particularly relevant in the present day with seemingly perpetual wars against terror, redistributing socialism reigns almost supreme and where popular demagogues threaten liberty and the essence of America's constitutional government.

In this Part 2 concluding essay the relationship of civilian disarmament to tyrannical governments and genocide is explored. Incidents in which liberty has been extinguished because firearms have been banned and civilians disarmed by increasingly oppressive governments; and the converse, countries where freedom has been preserved by armed citizens are also described.

We conclude that guns in the hands of law-abiding citizens deter crimes, and nations that trust their citizens with firearms have governments that sustain liberty and affirm individual freedom. Governments that do not trust their citizens with firearms tend to be despotic and tyrannical, and are a potential danger to good citizens - and a peril to humanity.
