Los Angeles is first in US to install subway body scanners

Passengers who choose not to be screened won

Los Angeles’ subway will become the first mass transit system in the US to install body scanners that screen passengers for weapons and explosives, officials said.

The deployment of the portable scanners, which project waves to do full-body screenings of passengers walking through a station without slowing them down, will happen in the coming months, said Alex Wiggins, who runs the Los Angeles County Metropolitan Transportation Authority’s law enforcement division.
