Ever since the deadly February shooting at Marjory Stoneman Douglas High School, students and parents have been sharing alarming stories. On Wednesday, podcaster Sarah Wine-Thyre tweeted the about picking up her 12-year-old daughter after their school was on a lockdown because of the presence of an 鈥渦nknown intruder.鈥 Wine-Thyre shared her daughter鈥檚 immediate thoughts and impressions of the frightening event. The tweets went viral, prompting a discussion of students鈥 fears for their safety in school 鈥 and whether, in trying to keep students safe, we鈥檙e inadvertently making them more afraid.

Wine-Thyre tweeted that her daughter and friends did not get updates about what was happening throughout the 41-minute lockdown. Her daughter also told her that she 鈥渒new this was for real,鈥 because it felt unlike drills the students have participated in. The students were huddled in a corner of a classroom without any information about why they were on lockdown. Many were sobbing.

鈥溾榃e were all sure we were going to die, Mom,'鈥 Wine-Thyre鈥檚 daughter told her. 鈥溾業鈥檓 so glad we didn鈥檛 die.'鈥

Wine-Thyr鈥檚 tweets can be seen as part of a larger conversation about student fears post-Parkland. Though school shootings are on the rise, they鈥檙e still a very rare occurrence. Yet, students and families have been reporting major fears in the months since nine people were killed in Parkland. They鈥檝e also been reporting incidents where an imminent threat was perceived, even if that perception was not accurate. The New York Times reports that 鈥渟cenes of gun threats, scares and lockdowns have played out around the country dozens of times each day鈥 since the February shooting.

Student activists, who have been advocating for stricter gun laws and other reforms, have also sometimes claimed there is an 鈥渆pidemic鈥 of school shootings, and that violence in schools is the 鈥渘ew normal.鈥 But as Eric Levitz recently noted in New York, these claims have 鈥渓ittle basis in empirical reality.鈥 That is: school shootings, while horrifying and tragic no matter how often they occur, are not the norm.

According to the National Center for Education Statistics, .26 percent of public K-12 schools experienced a shooting during the 2009-2010 school year (the most recent stats the NCES has). The statistics include incidents where nobody was hurt. In March, David Ropeik, a risk perception and risk communications consultant, noted that the odds of a student being killed by a school shooter on any day since 1999 are one in 614,000,000, and that school shootings have in fact become less frequent overall since the 1990s.

But these figures don鈥檛 offset what appears to be widespread panic among kids and families. Further, any violence is cause for concern, and there鈥檚 still some risk that students and school staff may be harmed at school. In response to these threats, some schools have turned to the ALICE Training Institute, a for-profit 鈥渟ecurity training company鈥 formed in the wake of the Columbine shooting.

ALICE (which stands for Alert, Lockdown, Inform, Counter, Evacuate) was founded by two former police officers and a former educator. The controversial training program offered by ALICE encourages students and teachers not to merely be 鈥減assive鈥 during lockdown scenarios. The 鈥渃ounter鈥 part of the ALICE protocol includes attempting to confuse a shooter by throwing things or screaming.

The company also offers services to law enforcement, colleges, hospitals, and places of worship, among other institutions. School districts are the number one institution that uses ALICE鈥檚 services, followed by law enforcement departments. The Training Institute claims to have provided services to 3,700 K-12 school districts. A 2017 article in Education Week noted that ALICE became more popular following the 2012 shooting at Sandy Hook Elementary School.

While lockdowns have been credited with saving lives during school shootings, there isn鈥檛 yet any evidence that ALICE鈥檚 more aggressive 鈥渃ountering鈥 tactics are effective.

More and more schools have been running drills or using ALICE programs in the last several years, according to Education Week. But some experts are critical of ALICE, arguing the protocols are potentially dangerous and not supported by evidence. Ken Trump, a school safety consultant and vocal critic of ALICE told NPR in 2012 that, 鈥淢ost middle-school kids can鈥檛 decide between chicken nuggets and pizza for lunch [so] to think that we鈥檙e gonna put that liability and responsibility in the hands of a seventh-grader is insane.鈥

Michael Dorn, executive director of the non-profit campus safety organization Safe Havens International, has also criticized ALICE. In 2015 he said of the training program, 鈥淧eople are being conditioned for the wrong situations and in the wrong ways. I know it鈥檚 all meant well, but at the end of the day, it may waste a lot of money and time and may not make the schools that much safer. And that is our priority.鈥

While school shootings are very rare, they do happen sometimes, and nobody wants kids and school staff to be unprepared. How exactly to get everyone prepared is the subject of some debate, but experts have their doubts about aggressive tactics. In the meantime, there鈥檚 also a need to address the much more common and prevalent concern of students鈥 daily fears.
