Since 1999, there have been more than 430 school shootings across the nation. Oregon alone has had eight incidents since 2008, according to CNN. With school shootings being a concern for parents, teachers and students, a new industry around school safety has emerged. Estimated to be worth $4 billion, school shooting preparedness and security is projected to continue to grow. From panic buttons and bullet-resistant backpacks to drill simulations and AI gun detection software, the amount of products and services being sold to schools and districts varies wildly.

A new HBO documentary, “Thoughts and Prayers,” takes a look at this industry and follows students, teachers and community members during a mass-casualty event drill in Medford, Oregon. Directors Zackary Canepari and Jessica Dimmock join us to share more about the school security industry.
