WASHINGTON, Jan 25 (Reuters) - Half of the mass attacks in the United States from 2016-2020 were sparked by personal, domestic or workplace disputes, according to a new U.S. Secret Service report that aims to prevent violence by identifying warning signs.
The attackers were overwhelmingly men, often with histories of mental health symptoms, financial insecurity or engaging in domestic violence.
The report comes days after a pair of mass shootings in California took the lives of 18 people and as authorities searched for motives in the attacks, both linked to older men.
The attacks targeted workplaces, schools, religious institutions and public transportation, among other locations, killing 513 people and injuring 1,234.
State-level "red flag laws" that allow for the court-ordered removal of guns from someone presenting a risk could limit such attacks, the report said.
