A school shooting is an armed attack at an educational institution, such as a primary school, secondary school, high school or university, involving the use of a firearm. Many school shootings are also categorized as mass shootings due to multiple casualties.[1][2] The phenomenon is most widespread in the United States, which has the highest number of school-related shootings,[3][4] although school shootings take place elsewhere in the world. Especially in the United States, school shootings have sparked a political debate over gun violence, zero tolerance policies, gun rights and gun control.
According to studies, factors behind school shooting include easy access to firearms, family dysfunction, lack of family supervision, and mental illness among many other psychological issues.[5] Among the topmost motives of attackers were: bullying/persecution/threatened (75%) and revenge (61%), while 54% reported having numerous reasons. The remaining motives included an attempt to solve a problem (34%), suicide or depression (27%), and seeking attention or recognition (24%).[6]
