Analyst: Turn the tables on TSA
Frost and Sullivan airport security analyst John Hernandez said the report isn't particularly surprising. The TSA has been plagued by uneven training for years, he said, resulting in a work force that isn't always properly educated about how to do their jobs.
"I think John Q. Traveler should not so much be concerned, but take an active role in security," he said. "As they are willing to point out things we do wrong, we should be ready to report on the failure in their security operations, as well."
The government report calls on the TSA to improve how the agency monitors and follows up on allegations of misconduct. The agency has accepted the recommendations, Halinksi said.
