In it's effort to make NYC even safer, and them as well, The New York Police Department has been testing a device that can detect guns from 16 ft. instead of having to preform physical searches, risking their lives should the people in question escape enough to make the situation dangerous. This device is developed with the help of the Department of Justice. This devices uses terahertz imaging detection to measure the amount of radiation that humans naturally emit. It then determines whether the flow of this radiation is impeded by a foreign object. In this case, a gun. During a speech Tuesday, Police Commissioner Ray Kelly said the device shows "a great deal of promise as a way of detecting weapons without a physical search." He also said that the technology will be only be deployed under "reasonably suspicious circumstances".
While this technology sounds exciting to some people, naturally some people have worries and concerns.
New York Civil Liberties Union executive director Donna Lieberman had this to say:
"We find this proposal both intriguing and worrisome," and added that the scanner could easily infringe upon civilian privacy.
She also came to say that:
"If the NYPD is moving forward with this, the public needs more information about this technology, how it works and the dangers it presents."
