Carrying weapons to school for protection: An analysis of the 2001 school crime supplement data

This study focused on the reasons why adolescents bring guns to schools. It is argued that the etiology for carrying other weapons to school is not the same as that for carrying a gun to school for protection. Data from a nationally representative sample of school youth were analyzed with an appropriate analytic technique—multinomial logistic regression in dealing with nominal dependent variable. The results supported the hypotheses that both correlates and correlational strengths of carrying guns and other weapons to school for protection are different. Such factors as others' drug use, gangs at school, skipping school, perception, and age influence the probability of carrying other weapons to school, but are not related to carrying a gun to school. The three factors that relate to both carrying a gun and other weapons to schools are physical fights, peers' carrying guns, and gender. Their correlational strengths, however, are quite different.     

Air guns: toys or weapons?

Air guns and blank guns may appear relatively harmless at first glance, but they are, in fact, potentially destructive, even lethal, weapons. Approximately 2 to 2.5 million nonpowder firearms are sold annually, and again approximately 12.9 per 100,000 population are treated for such injuries in hospital emergency departments each year in the United States. Unfortunately, these guns are considered to be a toy for children. Therefore, incidents of air gun injuries are gradually increasing. Although such injuries may initially be considered trivial, it may signify severe internal tissue pathologies. These apparently trivial injuries may have catastrophic consequences if unnoticed. In this study, we report 4 cases with head injury due to a shot by these guns. The cases indicate that these people had used the guns belonging to their parents for the purpose of suicide. The cases also show that these machines are not innocent.     

DOES GUN PREVALENCE AFFECT TEEN GUN CARRYING AFTER ALL?*

Previous research suggests that American adolescents usually have ready access to guns, and that the extent of misuse of guns by adolescents is not much affected by local gun prevalence or regulation. This “futility” claim is based on one interpretation of survey data from several cities, but has not been tested directly. Here we do so using microdata from a nationally representative survey, the 1995 National Survey of Adolescent Males. Using the restricted geo‐coded version of these data, and conditioning on an extensive set of covariates, we find (among other results) that the likelihood of gun carrying increases markedly with the prevalence of gun ownership in the given community. We also analyze the propensity to carry other types of weapons, finding that it is unrelated to the local prevalence of gun ownership. The prevalence of youths carrying both guns and other weapons is positively related to the local rate of youth violence (as measured by the robbery rate), confirmatory evidence that weapons carrying by youths is motivated in part by self‐protection.     

Death caused by projectile guns--a retrospective analysis of 34 cases in Berlin and Hamburg

The autopsy material of the institutes for forensic medicine in Berlin/GDR and Hamburg was analyzed retrospectively (period from 1961 till 1987; 70,000 autopsies) for fatalities caused by "humane killers" (n = 22) and stud guns (n = 12).-Epidemiological, criminological and morphological findings: The decreased were all men aged between 18 and 75 years (mean 48 years) except one 61 year-old paraplegic women who was killed by her husband with a humane killer. The great majority of cases consisted of suicides; two accidents at work were caused by stud guns. These unusual weapons are normally used by skilled people (i.e. butchers or constructional workers respectively). The fatal wounds were situated at the head, especially the forehead, seldom at the nape of the neck or in the mouth, or sometimes in the chest when using stud guns. Combined suicides (especially together with hanging) are not unusual. Survival periods (with or without acting capacity) can range between minutes or even months (after neurosurgical intervention).-The frequency of such unusual and overall rare cases did not raise during the investigation period.     

Observations and statistics relating to suicide weapons

The weapon at the scene of a suicide provides a resource in addressing such questions as frequency of blood in or on the weapon, location of the weapon with respect to the body, and evidence of firearm discharge residues on the hand. The first 195 weapons were tested for blood by a technique different from the following 202 weapons. Results were obtained which caused procedural changes in blood detection. Data are presented for frequency of blood in and on the muzzle of weapons, relative frequency of location of suicidal gunshot wound, and percent "positive" findings of gunshot residue metals on the hands. It was found that suicidal gunshot wounds were 3 times more frequent to the head than the chest, and that no significant difference was noted between males and females in this study. Scene photographs reveal that the suicide weapon is in or resting on the hand of the decedent 20% of the time with handguns and 11% of the time with long guns.     

Comparison of wound morphology following gunshots by machine guns and sub-machine guns

Automatic weapons such as machine guns and submachine guns are found in the German-speaking region only in special army and police units and appear accordingly rarely in homicides, suicides and accidents. In the following, the findings in two cases of death with the use of machine and submachine guns are presented. The first case was a fatal accident during shooting on a training area (current machine gun of the German army, calibre 7.62 x 51 mm), the second case was a killing during a physical conflict (submachine gun MP 40 from World War II, calibre 9 x 19 mm). In the case with the machine gun autopsy disclosed typical entry holes corresponding to the calibre, but unusually large exit wounds with tissue bridges in the wound ground, measuring 4 x 2.5 cm in diameter. By contrast, the second case (submachine gun) showed "normal" entry and exit wounds. The differences are mainly caused by deviating ballistic data of the ammunition used. They are discussed against the background of literature on wound ballistics.     

WEAPON EFFECTS AND INDIVIDUAL INTENT TO DO HARM: INFLUENCES ON THE ESCALATION OF VIOLENCE*

In order to assess the roles of weapons and offender intentions in the outcomes of potentially violent events, we analyze more than 2,000 incidents described by offenders. We advance the study of weapons effects through a within‐person analysis that lets us control for all time‐stable characteristics of the offenders. Thus, we address the concern that relationships between type of weapon and incident outcome may be spurious because individuals with a greater propensity to do harm are more likely to use guns. Findings indicate that weapons have independent effects that differ across the stages of an event.     

Packing Heat: Attitudes Regarding Concealed Weapons on College Campuses

Gun violence at American colleges and universities has rekindled the debate surrounding concealed weapons on campus. This study examined college student and faculty opinions on two college campuses, focusing on their attitudes towards private citizens carrying concealed guns on campus. Data were collected during the fall 2008 and spring 2009, and over 2,100 students, staff, faculty, and administrators on the two campuses participated in the research. The results indicate over 70 % of respondents oppose the option of carrying concealed guns on campus. In addition, the idea of more guns on campus makes the majority of students and faculty feel less safe, and allowing concealed weapons serves to decrease the sense of campus safety. This study continues to empirically advance the argument that those who live, work, and study do not want more guns on campus. Further research in this area, including an expanded range of the nation’s college campuses, should be explored.     

Accidental death with tear gas pen gun: a case report.

A case of accidental death resulting from a dropped tear gas pen gun is described. Tear gas pen guns can be easily altered to fire regular ammunition and can accommodate a variety of ammunition. Other similar pocket-sized weapons are mentioned.     

Gun Availability and Robbery Rates: A Panel Study of Large U.S. Cities, 1974–1978

This paper examines the hypothesis that crime rates and the availability of firearms form a "vicious circle," so that increases in one lead to increases in the other. Two waves of panel data are used to estimate the relationship between rates of robbery and the relative availability of guns in a sample of large U.S. cities. The results indicate that total robbery rates and gun availability had no influence on each other, but that weapons choice in robbery and gun availability did form a mutually reinforcing cycle. Some implications of these findings are considered.     

Experimental Effect of Shots Caused by Projectiles Fired from Air Guns with Kinetic Energy Below 17 J

Pursuant to the Polish Weapons and Ammunitions Law (Legal Gazette No 53/1999 item 549 with subsequent amendments), air guns with kinetic energy of the fired projectiles below 17 J are not regarded as weapons. The aim of the study was to assess the potential effect of shots caused by projectiles of various mass and structure fired from air guns with kinetic energy below 17 J on human soft tissues. As a model of soft tissue, we used 20% gelatin blocks. After shooting, we measured the depth of gelatin block penetration by pellets fired from various distances and compared these results with autopsy findings. The results demonstrated that examined pneumatic guns may cause serious injuries, including damage to the pleura, pericardium, liver, spleen, kidneys, femoral artery, and thoracic and abdominal aorta. Experiment shown that gelatin blocks do not reflect fully the properties of the human body.     

Unusual homicide by air gun with pellet embolisation.

A homicidal case by an air gun involving a 73-year-old woman who was found dead in her home is described. At autopsy, two gunshot wounds were observed on the left anterior chest and the right back. There was neither exit wound nor powder burns. The fatal pellet, 0.9 g and 5.5mm diameter, penetrated the left anterior chest and the heart to cause cardiac tamponade (200 ml) before lodging in the left subclavian artery. Death was due to cardiac tamponade.This case has exhibited two rare phenomena: homicide by an air gun and pellet embolisation. This is the first homicide case by use of air gun in Japan and demonstrates that although it may be rare, air guns can be used as potential homicidal weapons. This experience will alert our society and others on the potential hazards of air guns we have tended to regard as toys.     

THE FACTUAL FOUNDATION FOR CERTAIN KEY ASSUMPTIONS OF GUN CONTROL

The case for legal restrictions on gun ownership and use as a strategy for reducing criminal violence relies on factual assumptions about the nature of gun ownership and violent behavior. Five of the most crucial ones are identified and subjected to a comparison with the available empirical evidence. All of the following assumptions were found to be substantially at variance with the evidence: (1) Guns are five times deadlier than the weapons most likely to be substituted for them in assaults in which guns are not available. (2) The sight of a gun can elicit aggression, due to the learned association between guns and violence. (3) If guns are made more expensive, more difficult to obtain, or legally risky to own, people will do without them. (4) Guns are useless for self-defense or protection of one's family, home, or business, and have no deterrent effect on criminals. (5) Homicides are largely "crimes of passion" committed by otherwise law-abiding citizens not distinguishable from other people. Therefore, control must be directed at all gun owners rather than select criminal subgroups.     

Trends in Converted Firearms in England & Wales as Identified by the National Firearms Forensic Intelligence Database (NFFID) Between September 2003 and September 2008

Abstract: The National Firearms Forensic Intelligence Database (NFFID © Crown Copyright 2003‐2008) was developed by The Forensic Science Service (FSS) as an investigative tool for collating and comparing information from items submitted to the FSS to provide intelligence reports for the police and relevant government agencies. The purpose of these intelligence reports was to highlight current firearm and ammunition trends and their distribution within the country. This study reviews all the trends that have been highlighted by NFFID between September 2003 and September 2008. A total of 8887 guns of all types have been submitted to the FSS over the last 5 years, where an average of 21% of annual submissions are converted weapons. The makes, models, and modes of conversion of these weapons are described in detail. The number of trends identified by NFFID shows that this has been a valuable tool in the analysis of firearms‐related crime.     

Characteristics of firearms and gunshot wounds as markers of suicide.

Data from a total of 1,200 cases that the Medical Examiner of Dallas County, Texas, ruled as suicide with a firearm have been compared with the results of forensic laboratory examinations and tests; 75% are with handguns and 25% are with long guns. The incidence of suicides by gender yields 82% males and 18% females, with the most common entrance site being the head. With regard to racial distribution of persons committing suicide, > 88% are white in the study population group, which is 76% white. Data are presented for the incidence of blood detected inside and on the muzzle end of the barrel of the firearm, and for the persistence of blood inside the barrel even after the weapon was discharged to obtain test bullets. The analysis of handwipings for primer residues shows that "positive" results are obtained for approximately 50% of the revolvers and approximately 32% of the pistols when the caliber is > 22. Other projects such as transfer of gunshot residues to the hand by simply handling the weapon, the incidence of single-contact wounds in homicide versus suicide cases, and the percent of positive identification of bullets with weapons submitted are described.     

The criminal use of improvised and re-activated firearms in Great Britain and Northern Ireland.

Following the Hungerford Massacre the British Government imposed additional strict firearms legislation in 1988 that involved several classes of arms being placed into the prohibited category. By way of compensation a scheme was introduced to allow the unrestricted possession and transfer of the newly prohibited arms, other firearms and "prohibited weapons", if de-activated to a standard acceptable to the Secretary of State. Approved standards for firearm de-activation were drawn up in 1989. The inspection of the de-activated arms was devolved to the two Gun Barrel Proof Houses at London and Birmingham, as otherwise the task of inspecting the thousands of guns involved would have overloaded the firearms section at the Huntingdon Forensic Science Service Laboratory, who were already dealing with criminal firearms cases submitted by 41 of the 43 police forces throughout England and Wales, as well as providing technical assistance to the Home Office and Government Ministers. Members of the Gun Trade made representations to the Minister involved during the initial stages of setting up the official de-activation standards. This resulted in some measure of compromise in the range and nature of the de-activation requirements. Although it was clear that some individuals possessing the necessary skill and equipment might attempt to restore the odd weapon to a working condition, the scheme appeared to work reasonably well for the next few years. However, over the passage of time, criminal casework submissions to the Huntingdon Laboratory from industrial city areas along the M62 corridor of northern England revealed a steadily growing trend in the use of re-activated arms, which in a significant number of cases involved the use of fully automatic weapons. At first, the nature of the re-activation processes used to restore these arms was quite crude. However, with the passage of time a steady improvement in the machining and welding skills used by the some of the culprits involved became more and more apparent, as was a move by them to bulk restoration. The use of restored arms in serious and often drug related crime, spread to the other mainland British cities, and eventually to Northern Ireland. More rigorous de-activation standards were introduced in 1995 to help counter this perceived threat, particularly in respect of handguns and full-automatic weapons. Blank cartridge pistols and air cartridge pistols were also being modified to allow their use with bulleted ammunition in the commission of criminal offences. As a result all air cartridge guns were placed into the prohibited weapons category in 2003, and the possession of imitation firearms in a public place without good reason, also became an offence. The Government is now considering further legislation, which will affect the sale of replica firearms and cartridge reloading equipment and materials.     

Homicidal manual strangulation and multiple stun-gun injuries.

Stun guns are electric shock devices that are used by a number of law enforcement agencies to subdue violent offenders, but sometimes are discharged into human bodies as offensive weapons. We autopsied a 22-year-old woman who was strangled and had many stun-gun injuries on her head, chest, abdomen, arms, and legs. The stun-gun injuries consisted of many pairs of round erythemas with or without central paleness, some of which were accompanied by circumferential abrasions. To determine whether the electric shocks were administered before or after her death, we studied stun-gun injuries on pigs before and after death and found that the shocks after death did not mark the animal skin. Based on this experiment, all of the stun-gun injuries on the victim's body were concluded to have been inflicted before her death.     

The specificity of injuries inflicted by shots made from remade and self-made guns with silencers

Discussed in the paper is a complex forensic medical evaluation of injuries inflicted by shots made from a variety of hand guns with silencers. An experimental study denoted the specificity of close-distance entry wounds at shots made from remade or self-made guns with silencers; the quantitative and qualitative differential diagnostics was possible in such cases.     

Violence,Guns, and Suicide in New Orleans: Results from a Qualitative Study of Recent Suicide Decedents

Many Americans own guns to protect themselves against other people, but there is evidence that both victimization and gun access increase suicide risk. We conducted qualitative interviews with informants of 17 suicide cases in New Orleans of the 60 who died between January 2015 and April 2016 to understand the relationship between past trauma, gun access and storage, and suicide. Nine cases had experienced a past trauma, including three who had recently had a family member killed by homicide. Eight died via firearm; of those, seven owned the guns they used to take their lives and stored them locked (but loaded) at home or in their cars. Preventing community violence and addressing its sequelae may be important for reducing suicides. A multi‐pronged strategy consisting of policies, education, and marketing will likely be needed to address the risk of suicide conferred by gun access.
