On March 18th, the Los Angeles World Airports (LAWA) released to the public the after action report of the November 1, 2013 active-shooter incident that resulted in the death of a TSA Agent Gerardo Hernandez, and the wounding of two other agents and one passenger.

After action reports are not designed to point fingers or place blame. They are designed to identify what happened, what could have been prevented, what worked well and what improvements can be made in response to future events. They are a learning tool for planning and implementing various response and emergency management processes.
