Targeted school violence incidents routinely have warning signs
A Secret Service study showed there are clear predictive indicators.
The United States Secret Service and the United States Department of Education studied targeted school violence incidents and found behavioral warning signs that caused others to be concerned in 93% of cases. The Secret Service National Threat Assessment Center studied 41 school attacks from 2008 to 2017 and found that none of the school shootings were impulsive acts and all of them could have likely been prevented. The study found most of the weapons students used came from their home, many of the shooters were absent from school in the days prior to the shooting because they were suspended due to bad behavior, the disgruntled students were often treated poorly and teased by classmates in person and online, and some of the students exhibit mental health disorders and/or were suicidal. More than 75% of the attacks were in response to some sort of incident between the shooter and another student. More than half the attacks also involved the shooter and a gripe with a school administrator, however. As the number of school shootings increases and the details of the shooters and their methods are made public, so too are the troubled students who want to emulate them. Contrary to what people might think, the majority of the attackers actually came from two-parent homes and the families sometimes had deep community ties. About half of the attackers were actually doing well in school, with less than 5% failing classes.
