School shooting
A school shooting is an armed attack at an educational institution, involving the use of a firearm. Many school shootings are also categorized as mass shootings due to multiple casualties. The phenomenon is mostly widespread in the United States, which has the highest number of school-related shootings, outnumbering the six other G7 nations combined by a factor of 57 (2009–2018). 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. The top motive of attackers was being bullied, persecuted, or threatened (75%), followed by revenge (61%), while 54% reported having multiple reasons. The remaining motives included an attempt to solve a problem (34%), suicide or depression (27%), and seeking attention or recognition (24%).
