[ti:US Report on School Shootings Suggests Most Are ‘Preventable’]
[00:00.04]A new study suggests that many of the deadly school shootings in the United States
[00:06.52]over the past 10 years could have been prevented.
[00:12.56]Most students who carried out such an attack had shown threatening or suspicious behavior,
[00:20.00]but were not reported to law enforcement, the study found.
[00:26.12]The U.S. Secret Service reported the findings last week.
[00:32.20]The study was based on an in-depth examination of 41 incidents of "targeted school violence."
[00:41.60]All of the attacks happened over a 10-year period from 2008 to 2017.
[00:51.00]The Secret Service's National Threat Assessment Center collected information
[00:57.44]from police reports, as well as public and non-public investigation records.
[01:05.72]The findings will be used to train school officials and law enforcement
[01:11.21]to better identify students who may be plotting an attack.
[01:17.24]Lina Alathari is head of the National Threat Assessment Center.
[01:24.08]She told The Associated Press that most school shootings "are not sudden,
[01:29.80]impulsive acts where a student suddenly gets disgruntled."
[01:34.82]She added that "the majority of these incidents are preventable."
[01:41.64]In 80 percent of the shootings, the attacker's behavior was so worrisome to others
[01:48.21]that it made them express concern about "the safety of the attacker or those around them."
[01:56.12]The study found that the shootings took place quickly and often ended within 60 seconds or less.
[02:05.08]Law enforcement rarely arrived while the attack was happening.
[02:10.40]Attacks generally started during school hours and happened in a single area,
[02:16.40]such as a dining hall, restroom or classroom.
[02:22.04]Most of the attackers were male, but seven were female.
[02:27.56]Researchers reported that 63 percent of the attackers were white.
[02:32.72]Fifteen percent were black, 5 percent Hispanic and 2 percent American Indian or Alaska Native.
[02:43.52]The attackers most often used guns, but knives were sometimes used.
[02:50.32]Investigators said most of the weapons came from the homes of the attacker.
[02:57.44]The report identified warning signs that school officials,
[03:01.84]families and other students could use to help them recognize a possible attacker.
[03:10.36]These include signs of increased anger, a clear interest in weapons and violence,
[03:17.52]depression or isolation, self-harm or sudden behavioral changes.
[03:25.64]The study found most U.S. schools have security cameras
[03:30.21]as well as planned lockdown measures for shooting situations.
[03:36.48]However, only 17 percent of the schools had a system in place
[03:41.90]where students or families can directly contact officials about a student in crisis.
[03:50.28]The study was launched following the 2018 shootings
[03:54.44]at Marjory Stoneman Douglas High School in Parkland, Florida.
[04:00.56]The fathers of three students killed in the attack
[04:04.01]attended a media event timed to the release of the study.
[04:10.08]Tony Montalto, whose daughter Gina Rose died in the Florida shooting,
[04:15.84]said the research was invaluable and could have helped her school prevent the attack.
[04:23.64]"My lovely daughter might still be here today," he said.
[04:28.52]"Our entire community would be whole instead of forever shaken."
[04:34.76]Montalto urged other schools to pay close attention to the findings.
[04:41.04]"Please, learn from our experience. It happened to us,
[04:45.61]and it could happen to your community, too," he said.
