The New York City Police Department is developing a new way to seek people who are carrying firearms on the street. They plan to use radiation scanners, which could detect persons carrying guns, according to NYPD's Top Cop.
This cutting edge technology — which works with infrared imaging detects a natural energy, known as terahertz radiation, that emits from a person’s body, Kelly said during his State of the NYPD address.
Because the radiation waves cannot see through metal, a concealed gun could be detected from the image captured by the lens of the detector.
