In the summer of 2014, Anthony McGinty and Michelle Sosa were hired by Los Angeles World Airports to lead a unique, new classified intelligence unit on the West Coast. After only two years, their global scope and analytic capabilities promise to rival the agencies of a small nation-state. Their roles suggest an intriguing new direction for infrastructure protection in an era when threats are as internationally networked as they are hard to predict. ... their current operation falls somewhere between a start-up and a think tank. Because she came from an intelligence background, Sosa had an eye for big-picture narratives; McGinty’s 25 years as a street detective and war veteran gave him tactical insights and a deep knowledge of police culture. Together, the two of them have brought classified in-house intelligence analysis to one of the world’s busiest airports ... Their work promises to propel the city’s aging airport to the forefront of today’s conversations about what it means to protect critical infrastructure and, in the process, to redefine where true power lies in the 21st-century metropolis. ... More than 50,000 badged employees report to work there each day, many with direct access to the airfield—and thus to the vulnerable aircraft waiting upon it. More than 100,000 passenger vehicles use the airport’s roads and parking lots every day, and, in 2015 alone, LAX hosted 75 million passengers in combined departures and arrivals.
