MIAMI - The conversation on how to stop an active shooter has sparked decades of controversy and debates, but a University of Miami professor says their scientifically-backed invention could help pave the way to stop an aggressor in their tracks.

"About 80 percent of how we take in the world is visual," said Brian Arwari, a UM associate professor.

Arwari and his team created Lightguard Security, a device that has the power of 30,000 lumens. Once activated it is so bright that it would cause temporary blindness to an aggressor and disorientation.
