In "Undercurrents," Charlie examines the algorithm used to flag dangerous containers entering the country through the Port of Los Angeles. The flagged containers are then subject to more intense inspection. Because the actual search criteria are not made public, this activity looks at a fictional algorithm similar to the type that could be used.
