The police do not need individualized suspicion in order to conduct a search for purposes of airport security. The law in the Ninth Circuit expressly allows "blanket" administrative searches (i.e., searches for weapons or explosives conducted without individualized suspicion) so long as they are reasonable under the circumstances. E.g., United States v. Aukai, 473 U.S. 1265 (9th Cir. 2007).
