The Transportation Security Administration recommended that armed law enforcement officers be posted at airport security checkpoints and ticket counters during peak hours after a review of nearly 450 airports nationwide after last year’s fatal shooting at Los Angeles International Airport, The Associated Press reports.

The 25-page TSA report to Congress makes 14 recommendations that would not cost money, but are somewhat dependent on local authorities who provide airport security. Recommendations include requiring unarmed TSA employees to train for active shooter incidents, and the report specifically discarded the notion of creating an armed TSA officer unit.

The TSA also recommended installing more panic alarms, testing them weekly, and having them linked to security cameras. The review found that about two percent of panic buttons in airports nationwide were not working.
