In 2002, in response to a terrorist shooting incident at LAX, Mayor James Hahn directed that additional LAPD officers be assigned to the airport. These officers are assigned to passenger screening stations so as to free up Airport Police officers for other duties. The LAPD officers are trained by Airport Police for these duties and are expected to call Airport Police to resolve matters as they arise. LAPD officers assigned to this function are on overtime, with Los Angeles World Airports reimbursing LAPD and the Transportation Security Administration providing significant reimbursement in turn to the airport.
