Transportation Security Administration (TSA) checkpoint screeners are receiving training to prepare them for the possibility of a mass shooting at one of the agency’s airport checkpoints, and those TSA personnel are being instructed to “save themselves” should a shooting occur.
It is unclear whether the TSA is conducting the reported mass shooting scenario training at airports around the nation or only at the airport where our source, a veteran of the TSA, is assigned. The TSA source claims with obvious concern that his own life, along with the lives of other unarmed TSA personnel, would be in grave danger were an airport checkpoint shooting to unfold.
The TSA screener, who claims to have recently undergone agency training during which TSA personnel were confronted with a chilling checkpoint shooting scenario, now tries to remain aware of how to get out alive were such a shooting to unfold.
“Every day when I arrive for work, I look for an escape route in case someone opens fire,” said the TSA worker. “We have been told to save ourselves.”
Does the TSA already have intelligence about a possible future checkpoint shooting?
