A U.S. Secret Service report concludes that nearly all mass attacks on schools, churches, and businesses in 2018 were preceded by threats. Two-thirds of the attackers had mental issues, according to the report, and one-third had a history of serious domestic violence. Studied were 27 incidents in public places in which 91 people were killed and 107 injured, including the Feb. 14 massacre at Marjory Stoneman Douglas High School in Broward County.
