The thought of leveraging immediate technology solutions reflects both men's professional backgrounds: Button owns a telecom company, and Crane is director of sales, network security, and cloud management for a cloud-computing subsidiary of Dell Technologies. So far, their startup, Shielded Students, has enlisted three security companies: an emergency response coordination service and two that make gun detection systems. One of these systems, developed by Patriot One Technologies in Canada, integrates a microwave radar scanner with a popular artificial intelligence (AI) technique that is trained to identify guns and other hidden weapons. Shielded Students hopes to combine these and other solutions into a package that can help prevent another mass shooting like the one that killed Luke and 16 other people. "I can tell you with a lot of confidence that this technology, incorporated into Marjory Stoneman Douglas, would have probably saved all 17," Button said, "including my nephew–who was one of first people shot."
