Bus passengers in Pittsburgh will be observed today by TSA agents, Port Authority Police and first responders as part of a “security exercise."
According to CBS Pittsburgh, the Port Authority says the city's transit system is being used as a test location (video below).
The "security exercise" is being led by the TSA Mass Transit and Passenger Rail Division to detect and prevent any terror threats or attacks.
A similar TSA “security exercise” happened in Houston, Texas in 2012, but didn't go so well, reported ABC 13 (video below).
