Passengers boarding subway trains in Los Angeles may soon be shuffled through airport-style body scanners that are aimed to detect firearms and explosives.

A two-day pilot program by the Los Angeles County Metropolitan Transportation Authority began Wednesday. But officials quickly experienced a hiccup when a scanner being demonstrated Wednesday morning at Union Station malfunctioned before passengers could be put through the machine.

The machines use sensors to scan a person as they walk through, searching for firearms and , said Dave Sotero, a Metro spokesman. Passengers don't need to unload laptops or take off their jackets or shoes as the radio waves scan them to detect anomalies.

"It is specifically designed to test for mass-casualty threats," Sotero said. "The technology enables the system to locate on the body where there is a potential threat, and it appears on a video screen."

Metro is conducting the pilot program to evaluate the accuracy and capacity of the portable and determine if the scanners could become permanent fixtures in the Los Angeles transit system.

Each machine is designed to scan about 600 people per hour, Sotero said. About 150,000 passengers ride on Metro's Red Line daily, he said.

"This is designed so you don't have to wait," Sotero said. "The idea is that you have a continuous flow of people through the security system without causing a backlog and causing people to miss their trains."

Similar to airport checkpoints, when someone passes through the scanner, they are held for a few seconds while watch a monitor that shows the location on any anomalies the body. Several security officers stood guard at the screening checkpoint at Union Station on Wednesday morning. Large signs advised passengers that the screening is voluntary.

The scanners sell for about $60,000 each, said Chris McLaughlin, a vice president with Evolv Technology, which makes the system.

"I think it is a good idea with everything that has been going on and ISIS," passenger Jazmin Rosales, 29, said. "As long as it doesn't take too long, at least you know you can feel safe."

These are 'terahertz' scanners, after signal frequency used to scan the person. Akin to radar, it is better at picking up the soft tissue, and can see through clothes. First used in Florida airports, its output is a picture of a naked person, its clothes a pale shadow in the image. Keys on the water in the image scanned; as WE are over 92% water, our naked body is reproduced with all of its imperfections. Weapons are opaque to terahertz waves and show up starkly, being metal or other hard material with non natural shapes. Clinton's Attorney General Janet Reno volunteered to be one of the first users of the device, demonstrating that if SHE was willing to be 'voyeured', then it was 'safe for the rest of us to hang out our privates for puerile perusal. Airport security guards then 'thrust' to the 'forefront' of the privatcy invasion revulsion revolution. This is the truth the above article did not admit to the public but was 'all over' the media back in the 90's when it was new.
