[7] In a previous report of 18 school shootings by the Federal Bureau of Investigation (FBI), they released a profile that described shooters as middle-class, lonely/alienated, awkward, Caucasian males who had access to guns.
While the pre-frontal cortex is developing, children and teenagers might possibly rely more on the brain part known as the amygdala; involving thinking that is more emotionally active, including aggression and impulsiveness.
[21] However, these assumptions on the detrimental effects of "non-traditional" family structures have repeatedly been shown to be false, with the true issues lying within socio-economic realities.
According to surveys commissioned by the National Institute on Drug Abuse, between 20 and 30% of teenagers used/abused illicit substances, a much higher rate than single mother households.
"[27] Understanding that socio-economic factors have greater effects on child development and emotional stability have led many to argue that single-parent and other non-traditional households should be afforded equivalent incentives by the state, as are afforded married households, and that focusing on family structure rather than family stability derails efforts to understand the realities of mass-shooters.
[29] One factor is that school shooters tended to isolate themselves, and "exhibited an obsessive quality that often led to detailed planning, but ironically they seemed to lack an understanding of the consequences of their behavior and thus may have a history of adverse encounters with law enforcement."
[32] Daniel Schechter, Clinical Psychiatrist, wrote that for a baby to develop into a troubled adolescent who then turns lethally violent, a convergence of multiple interacting factors must occur, that is "every bit as complicated...as it is for a tornado to form on a beautiful spring day in Kansas".
Students who are bullied tend to develop behavioral problems, depression, less self-control and poorer social skills, and to do worse in school.
[41] Criminologists Fox and DeLateur note that mental illness is only part of the issue, however, and mass shooters tend to externalize their problems, blaming others and are unlikely to seek psychiatric help, even if available.
McGinty and colleagues conducted a study to find out if people tended to associate the violence of school shootings with mental illness, at the expense of other factors such as the availability of high-capacity magazines.
This adds important nuance to the idea that larger schools are more prone to mass violence by showing that the stress associated with losing the personal support given in a smaller community is a weight on students.
[47] A 2016 opinion piece published by U.S. News & World Report concluded that 22% of mass murders are committed by people who suffer from a serious mental illness, and 78% do not.
[48] In a 2015 New Republic essay, Columbine author Dave Cullen describes a subset of school shooters (and other mass murderers) known as "injustice collectors", or people who "never forget, never forgive, [and] never let go" before they strike out.
The essay describes and expands on the work of retired FBI profiler Mary Ellen O'Toole, who has published a peer-reviewed journal article on the subject.
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.
[56] In the summer of 1966, two major stories broke: Richard Speck murdered eight women on a single night in Chicago, and Charles Whitman shot and killed 15 people from a clock tower at the University of Texas in Austin.
[citation needed] Seeing this, 18-year-old Robert Benjamin Smith bought a gun, and on November 12, 1966, he killed four women and a toddler inside the Rose-Mar College of Beauty in Mesa, Arizona.
[63] Recent premeditative writings were presented according to court documents and showed Joshua O'Connor wrote that he wanted the "death count to be as high as possible so that the shooting would be infamous".
[89] A United States Secret Service study concluded that schools were placing false hope in physical security, when they should be paying more attention to the pre-attack behaviors of students.
The researchers focused on questions concerning the reliance on SWAT teams when most attacks are over before police arrive, profiling of students who show warning signs in the absence of a definitive profile, expulsion of students for minor infractions when expulsion is the spark that push some to return to school with a gun, buying software not based on school shooting studies to evaluate threats although killers rarely make direct threats, and reliance on metal detectors and police officers in schools when shooters often make no effort to conceal their weapons.
They had the following findings: There have been many representations of American school shootings in films and TV shows produced by both United States and international production companies.
While films Elephant, We Need to Talk about Kevin, Beautiful Boy, and Mass are solely focused on the either the act or the aftermath,[92] many of the shows such as Criminal Minds, Degrassi: the Next Generation, Law and Order, and One Tree Hill investigate the crime for an episode or use it as a plot point for about half a season.
[93] One of the more provocative songs to come out of the Parkland, Florida high school shooting was "thoughts & prayers" from alternative artist/rapper grandson (born Jordan Benjamin).
[96] The National Rifle Association of America has proposed allowing teachers to carry weapons on school grounds as a means of protecting themselves and others as a possible solution.
[101][better source needed][102] One such example is the Mercaz HaRav Massacre, where the attacker was stopped by a student, Yitzhak Dadon, who shot him with his personal firearm which he lawfully carried concealed.
[104] In other cases, such as shootings at Columbine and Red Lake High Schools, the presence of an armed police officer did little to nothing to prevent the killings.
While immediate action may be extremely dangerous, it may save lives which would be lost if people involved in the situation remain passive, or a police response is delayed until overwhelming force can be deployed.
[115] In addition to Utah, Wisconsin and Mississippi each have legislation that allow students, faculty and employees with the proper permit, to carry concealed weapons on their public university's campuses.
Statistics on what percentage of teachers are actually armed are unavailable and in Israel, for example, the intent is to counter politically motivated terrorist attacks on high value, soft targets, not personal defense against, or protection from, unbalanced individual students.
[126] In 2019, the United States Secret Service released an analysis of targeted school violence, concluding the best practice for prevention was forming a "multidisciplinary threat assessment team, in conjunction with the appropriate policies, tools, and training".
