This point was addressed in the article: > But would a school where every student has a smartphone be safer than one in which only the adults have smartphones? Ken Trump, the president of National School Safety and Security Services, warns that using a cellphone during an emergency can increase safety risks. “During a lockdown, students should be listening to the adults in the school who are giving life-saving instructions,” Trump explains. “Phones can distract from that. Silence can also be key, so you also don’t want that phone noise attracting attention.” In addition, it seems to me that 300 parents rushing to the school in 300 cars would probably make things more difficult for first responders. I would add that if Haidt is correct that removing phones improves mental health, then the likelihood of school shootings might decrease as a result. In any case, if you're going to argue with the headline, you might as well respond to the relevant portion of the article.
