The details of what happened on the third floor of Parkland High School last February are excruciating, in part because some parents believe their children's deaths were avoidable, Nikolas Cruz spent six minutes and 41 seconds inside the building, If, students on the third floor had had more warning, or if law enforcement had the information to act faster, they might not have died, according to an investigation by the South Florida Sun Sentinel (the investigation also concluded there were errors by the Broward County police). A couple of MBA's from the University of Chicago's Booth School of Business say they have a way to make security cameras more effective tools to help information travel faster if there is a shooter in the building. No one was monitoring the security cameras at Parkland, according to the Sun Sentinel. At $20 per month per security camera, the students, who named the company Aegis AI, have developed AI software that watches security cameras, identifies guns and sends information into whatever information system an institution has developed. For a school with 100 cameras, that would be about $24,000 a year.
