UW-Madison Police are embracing old and new technology as they prepare to protect more than 44,000 students and 21,000 employees on a sprawling campus in case of an active shooter situation.

The department announced Thursday it will next spring pilot Hexwave, a new technology that can detect weapons without slowing down large crowds in the way metal detectors often do at the Kohl Center.
