From the CNN report:
So the technology didn't fail; it just didn't see the weapon because the shooter didn't present it properly to the camera. I see.AI gun detection software, which is used in all Metro Nashville Public Schools, failed to detect the shooter’s gun, district officials said Thursday. The technology, called Omnilert, didn’t spot the weapon because the shooter wasn’t close enough to cameras to get an accurate read and activate the alarm, the school district said.
“It does work, but it’s not going to work in every instance, in every spot based on where that weapon might be visible,” Sean Braisted, chief of communications and technology for the district, said in a news conference Thursday.
Omnilert CEO Dave Fraser said the safety and well-being of its schools is the company’s top priority. “Our hearts go out to the students, staff, families, and the entire Nashville community affected by this tragic event,” Fraser said in a statement to CNN Thursday.
“We can confirm that the Omnilert Gun Detect system is deployed at MNPS schools but in this case the location of the shooter and the firearm meant that the weapon was not visible,” Fraser said. “This is not a case of the firearm not being recognized by the system.”
I think this probably is a case of the firearm not being recognized by the system. Of course we could just make it harder for people to get firearms in the first place.
