Unpredictability
We incorporate an element of unpredictability to our operations so that terrorists can’t use the predictability of security measures to their advantage. That means we may change airport inspection routines on a daily or hourly basis. For example, some passengers may be randomly selected for additional screening at the checkpoint, rather than the ticket counter, or they may have their shoes or carry-on bags tested for explosive materials. At their local airport, they may see canine teams patrolling the area before the checkpoint on one trip and patrolling the check-in area on the next. By adding an element of unpredictability, would-be attackers can’t find patterns in our operations and use them against us.
