===Parental supervision===
"Studies have found that within offenders' families, there is frequently a lack of supervision, low emotional closeness, and intimacy".<ref name="GWPD_2015">{{cite journal|last1=Gerard|first1=F.J.|last2=Whitefield|first2=K.C.|last3=Porter|first3=L.E.|last4=Browne|first4=K.D.|title=Offender and Offence Characteristics of School Shooting Incidents|journal=Journal of Investigative Psychology and Offender Profiling|date=2015|volume=13|page=24|doi=10.1002/jip.1439|url=http://shura.shu.ac.uk/12138/3/whitfield%20-%20Characteristics%20of%20school%20shooting%20incidents.pdf}}</ref> In a 2018 publication, Dr. George S. Everly Jr, of [[The Johns Hopkins School of Medicine]] and [[The Johns Hopkins Bloomberg School of Public Health]] outlined an accumulation of seven, recurring themes that warrant consideration regarding school shooters.<ref name="Profiling School Shooters">{{cite web|url=https://www.psychologytoday.com/us/blog/when-disaster-strikes-inside-disaster-psychology/201803/profiling-school-shooters|title=Profiling School Shooters|date=March 2018}}</ref> 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." A criticism in the media of past shooters was questioning how so much planning could commence without alerting the parents or guardians to their efforts. However, this has proven to be as difficult of a question to answer as anticipating any of the past school shootings.

Data from the [[National Center for the Analysis of Violent Crime]] and [[Centers for Disease Control and Prevention]], covering decades of US school shootings, reveals that 68% of shooters obtained weapons from their home or the home of a relative. 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.<ref name="The gun’s not in the closet">{{cite news|url=https://www.washingtonpost.com/news/local/wp/2018/08/01/feature/school-shootings-should-parents-be-charged-for-failing-to-lock-up-guns-used-by-their-kids/|title=The gun's not in the closet|newspaper=[[The Washington Post]]|date=Aug 2018}}</ref> 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.<ref name="The gun’s not in the closet" /> Such incidents may also lead to nationwide discussion on gun laws.<ref>{{cite web|title=Government Vows to Take Action Following Kauhajoki Shootings |url=http://yle.fi/uutiset/govt_promises_action_following_kauhajoki_shootings/6112199 |access-date=September 23, 2008 |work=YLE|date=September 23, 2008 }}</ref>

The [[FBI]] offer a guide for helping to identify potential school shooters, ''The School Shooter: A Threat Assessment Perspective''.<ref name="The School Shooter, 1999">{{cite web|url=https://www.fbi.gov/file-repository/stats-services-publications-school-shooter-school-shooter/view|title=The School Shooter|date=1999}}</ref>

[[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".<ref>{{cite web|url=http://www.dana.org/news/cerebrum/detail.aspx?id=30762|title=Forecasting Aggression: Toward a New Interdisciplinary Understanding of What Makes Some Troubled Youth Turn Violent|website=Dana.org|date=Feb 2011}}</ref> Thus, reinforcing the issue that school shooters do not necessarily come from "bad" parents. No more than they could come from attentive, educated, negligent, single, married, abusive, or loving parents.
