Assessing Shooting Threats Is a Matter of Life or Death. Why Aren’t Experts Better at It?
The rise in school shooting threats is alarming — and a cry for help
School shootings are increasing — and changing. Easily accessible guns are to blame.

There is #nonotoriety for mass shooters. This guy should be #viral for shooting himself in the leg at an elementary school in Texas...2 days after one of the worst school shootings ever. Anthony White (55) charged with unlawful carrying of a weapon in prohibited places.
-
This guy shot himself in the leg with a handgun tucked in his waistband at Duff Elementary in Arlington, TX Thursday. School went on lockdown. As the country tries to make sense of what happened at Robb Elementary in Uvalde, this guy was carrying a gun into another Texas school.

@zeepetals @MichaelBluth20 @bnaikma @TwinDaddyDave @ThisIsOurLane @POTUS I still jump every time the shot is fired. It is pretty impressive that the first thing he says is "is everyone alright?".

@zeepetals @MichaelBluth20 @bnaikma @TwinDaddyDave @ThisIsOurLane @POTUS The most well known "accidental" shooting in a school has almost 2 million views on youtube. youtube.com/watch?v=vfONck…

Robb Elementary attacker was known as "school shooter" on Yubo (stream, chat, and group messaging app). Other users said they were not surprised when the attack happened. He had an account that was verified with his gov/school ID and phone number. This was preventable.
-
In 1980-90s, hostage and barricade situations occurred at schools across the country. Police surrounded and negotiated, like 1993 in KY, when student took 22 classmates hostage before surrendering. Post-Columbine, nation-wide switch to quick response and "active shooter".
-
Duff Elementary (Arlington, TX) went into lockdown yesterday when a man near the front office shot himself in the leg with a concealed handgun. At least 202 other "accidental shootings" at k-12 schools. Most involve parents, teachers, and police officers.
-
Texas man with concealed weapon shot himself in the leg on a school campus, and was taken to the hospital for treatment. One of more than 100 "accidental" shootings on school campuses. Most are by parents, teachers, and police officers. twitter.com/safeschools/st…

"1996 was a watershed moment in Australia and Britain, when governments finally decided to tackle gun violence after a gunman killed 35 people, and injured 23 more, in the Tasmanian tourist town of Port Arthur." via @irishexaminer citing K-12 SSDB data irishexaminer.com/news/spotlight…

@zhawke2002 That is incredible. Thank you for sharing.

@zhawke2002 This is beyond interoperability. Someone who is not directly involved in the intensity of the on-scene operations needs to be hearing the messages and putting together the picture of what is happening.

During the Las Vegas Harvest Festival shooting, communications failed between officers on the scene, their supervisors, the 911 center, and the incident commander. 5 years later at Robb Elementary in Uvalde, TX, these same issues have not been resolved. medium.com/homeland-secur…

Two BORTC agents who spoke to @thehill said CBP's tactical unit arrived at Robb Elementary School around 12:15 pm and were told not to enter school. After 30 minutes, federal agents decided to move in and take out shooter.
-
Per CBP official, Robb Elementary gunman emerged from a classroom closet and fired at Border Patrol tactical agents entering the room. Agents had a ballistic shield and fatally shot the gunman. (photo: BORTAC agents room entry training)

@CptEspinoza @brianstelter @ShimonPro That is an excellent point. I wrote this after the Las Vegas festival shooting. We may see the same situation where officers at the scene were providing important pieces of information that command was not hearing. medium.com/homeland-secur…

Riedman said there are only two American institutions that have an absolute prevention mission: TSA and Secret Service. "The baseline is zero attacks and we'll spend any amount of money to get there. This is not viable at a school." via @laurameckler washingtonpost.com/education/2022…
-
"[The attack] is honestly not surprising. It's a sad fact that it could have been stopped. It really could have." - Yubo user App blends livestreams, chats, private groups, and private message. Robb Elementary shooter was a verified user (gov/school ID photo uploaded & phone#)
-
School shootings are preventable. Someone who sees a red flag must take action. Robb Elementary attacker was known as "Yubo school shooter" on social media. Made violent threats to other users. Unknown user asked "should i message his classmates?"

David Riedman (@david_riedman), co-founder of the K-12 School Shooting Database, said he has recorded more than 2,500 instances of threats to carry out school shootings through media reports since 2018. via @washingtonpost washingtonpost.com/education/2022…

@maxschachter We have lots of data, lots of research, and lots of best practices. Our focus needs to be transforming those concepts into practice. If the same operational failures keep occurring, there is a fundamental problem that needs to be addressed.
