NYPD is testing a virtual pat down device
NYPD made public that they ar testing a virtual pat down device using technology that detects terahertz, which is the natural energy people and inanimate objects emit. Once something obstructs the radiation, like a concealed weapon, the device "highlights" that object so it is in clear view.
The scanners are worrying individuals who believe this technology violates their Fourth Amendment rights to be free from unreasonable searches and seizures.
The gun scanning technology will help lessen the need for NYPD's use of Stop and Frisk procedures that allowed officers to stop New Yorkers for random street interrogations or searches. In 2011, about 600,000-plus New Yorkers were stopped.
If authorized to carry the person would not be detained. If illegal then they would be detained and the gun taken off the street.
