Because security theater measures are often so specific ( such as concentrating on potential explosives in shoes ) , it allows potential attackers to divert to other methods of attack . This not only applies to the extremely specific measures , but can also involve possible tactics such as switching from using highly scrutinized airline passengers as attackers to getting attackers employed as airline or airport staff . Another alternate tactic would be simply avoiding attacking aircraft in favor of attacking other areas where sufficient damage would be done , such as check-in counters ( as was done , for example , in the attacks on Brussels airport on 22 March 2016 ) , or simply targeting other places where people gather in large numbers , such as cinemas
