After Uvalde shooting, tech companies tout their solutions. But do they work?

After the mass shooting at an elementary school in Uvalde, Texas, an all-too-familiar question emerged: how do we prevent such horror from happening again? A handful of companies have said they have tech solutions that could help. They included Drone firm Axon, which promoted a remotely-operated Taser device to be deployed in schools. EdTech companies, including Impero Software, said their student surveillance services could flag warning signs and help prevent the next attack. The companies are part of a thriving school security industry, one that has grown to $3.1bn in 2021 from just $2.7m in 2017, according to market research firm Omdia.
