My kids’ elementary school is having a lockdown drill today, so this is a reminder that, even with the school shootings you hear about in the news, school is by far one of the safest places children can be, there’s zero evidence that lockdown or active shooter drills improve safety, and their main effect is in traumatizing children by convincing them that school in fact isn’t safe. It’s shameful that schools do this to kids and parents should demand they stop.
