LOS ANGELES (KGO) -- The Los Angeles subway system will become the first in the U.S. to install body scanners.
The scanners are portable and will screen passengers for weapons and explosives.
The machines can detect suspicious items from 30 feet away and have the capability of scanning more than 2,000 passengers per hour.
About 150,000 passengers ride on Metro's Red Line daily and the subway system counted more than 112 million rides last year.
