In wake of several mass shootings across the country, organizations are looking for ways to be able to stop these situations before they get a chance to happen. Artificial intelligence that can detect the presence of firearms in public places and automatically lock potential shooters out of buildings sounds futuristic, but the technology is already here. Defendry is a company working on optimizing and spreading this software to keep the public safe. The idea behind the AI centers around preventing a shooter from being able to get to large groups of people, all while giving police and nearby security live updates on the shooter's description and location. "If you can keep someone out of the building, you've just mitigated a huge potential for further damage. Further deaths," said Pat Sullivan, founder and CEO of Defendry.
