is diagnosed as having a mental illness and who used high capacity magazines. One group read an article that presented only the facts of the case. A different group read an article about the same shooting, but in it the author advocated for gun restrictions for people with mental illness. Another group read about the shooting in an article that suggested the proposal to ban large-capacity magazines, which acted to advocate that shootings could stem from a societal problem rather than an individual problem. The control group did not read anything. Participants were then all asked to fill in a questionnaire asking about their views on gun control and whether they thought there should be restrictions on high-capacity magazines. 71% of the control group thought that gun restrictions should be applied to people with mental illness, and nearly 80% of participants who read the articles agreed. Despite the fact that the article exposed the readers to both the mental illness of the shooter, and the fact that the shooter used high-capacity magazines, participants advocated more for gun restrictions on people with mental illness rather than bans on high-capacity magazines. This suggests that people believe mental illness is the culprit for school shootings in lieu of the accessibility of guns or other environmental factors. The authors expressed concern that proposals to target gun control laws at people with mental illness do not take into account the complex nature of the relationship between serious mental illness and violence, much of which is due to additional factors such as substance abuse. However, the link is unclear since research has shown that violence in mentally ill people occurs more in interpersonal environments.

1052:"Bullying is common in schools and seemed to play a role in the lives of many of the school shooters". A typical bullying interaction consists of three parts, the offender/bully, a victim, and one or more bystanders. This formula of three enables the bully to easily create public humiliation for their victim. Students who are bullied tend to develop behavioral problems, depression, less self-control and poorer social skills, and to do worse in school. Once humiliated, victims never want to be a victim again and try to regain their image by joining groups. Often, they are rejected by their peers and follow through by restoring justice in what they see as an unjust situation. Their plan for restoration many times results in violence as shown by the school shooters. 75% of school shooters had been bullied or left behind evidence of having been

The student may have a TV in his own room or is otherwise free without any limits to spend as much time as he likes watching violent or otherwise inappropriate shows.

The student may know much more about computers than the parents do, and the computer may be considered off limits to the parents while the student is secretive about his computer use, which may involve violent games or Internet research on violence, weapons, or other disturbing subjects."

Since 1999, out of 145 US school shootings committed by children/adolescents, 80% of the guns used were taken from their homes or relative's home. The availability of firearms has direct effect on the probability of initiating a school shooting. This has led many to question whether parents should be held criminally negligent for their children's gun-related crimes. By 2018, a total of four parents were convicted of failing to lock up the guns that were used to shoot up US schools by their children. Such incidents may also lead to nationwide discussion on gun laws.

1020:"The parents set few or no limits on the child's conduct, and regularly give in to his demands. The student insists on an inordinate degree of privacy, and parents have little information about his activities, school life, friends, or other relationships. The parents seem intimidated by their child. They may fear he will attack them physically if they confront or frustrate him, or they may be unwilling to face an emotional outburst, or they may be afraid that upsetting the child will spark an emotional crisis. Traditional family roles are reversed: for example, the child acts as if he were the authority figure, while parents act as if they were the children."
821:(FBI), they released a profile that described shooters as middle-class, lonely/alienated, awkward, Caucasian males who had access to guns. The most recent report cautioned against the assumption that a perpetrator can be identified by a certain 'type' or profile. The results from the study indicated that perpetrators came from differing backgrounds, making a singular profile difficult when identifying a possible assailant. For example, some perpetrators were children of divorce, lived in foster homes, or came from intact nuclear families. The majority of individuals had rarely or never gotten into trouble at school and had a healthy social life. Some, such as

Therefore, most of the literature does not come from peer-reviewed sources but rather published news reports. In addition, most of these reports are not objective and clearly appear to support a specific side of the debate." So far, data has been inconclusive as to whether or not arming teachers would have any sort of benefit for schools. For years, some areas in the US have allowed "armed classrooms" to deter (or truncate) future attacks by changing helpless victims into armed defenders. Advocates of arming teachers claim that it will reduce fatalities in school shootings, but many others disagree.

weapon, and then use it against the teacher or other students." Some members of the armed forces have also had concerns with armed classrooms. Police forces in Texas brought up the potential for teachers to leave a gun where a student could retrieve and use it. "They are further concerned that if every teacher had a gun, there would be an unnecessarily large number of guns in schools (even including elementary schools). This large number of guns could lead to accidental shootings, especially those involving younger children who do not understand what guns do."

"In Berkowitz & LaPage's (1967) examination of this effect, students who were in the presence of a gun reported higher levels of aggressive feelings towards other students and gave more violent evaluations of other students' performance on a simple task in the form of electric shocks. This finding points to possible negative outcomes for students exposed to guns in the classroom (Simons & Turner, 1974; Turner & Simons, 1976)."

Between 2000 and 2010, counting incidents from 37 countries in which someone was injured or killed on school grounds, with two or more victims, and not counting "single homicides, off-campus homicides, killings caused by government actions, militaries, terrorists or militants", the number of such incidents in the United States was one less than in the other 36 countries combined; in the vast majority of the United States incidents, perpetrators used guns.

to be misguided or erroneous. Ferguson (2009) has argued that a third variable of gender explains the illusory correlation between video game use and the type of people who conduct school shootings. Ferguson explains that the majority of school shooters are young males, who are considerably more aggressive than the rest of the population. A majority of gamers are also young males. Thus, it appears likely that the view that school shooters are often people who play violent video games is more simply explained by the third variable of gender.

Centers for Disease Control and Prevention. An average 1,297 children die (two children per 100,000) and 5,790 are treated for injuries caused by guns each year, the study reported. Six percent of these deaths were accidental, 38% were suicides, 53% were homicides and the remaining 3% were from legal intervention or undetermined reasons. Guns injured children at a rate of 8 per 100,000 children, but this rate is likely considerably higher because of unreported injuries.
