They ARE looking for someone!
Probably one of the many reasons I grew up to be the questionable individual I am..... when I was a little kid for whatever reason it seemed like just about every night there would be those big double bladed military helicopters flying over our house - LOUD! When I would ask my mom what they were doing flying at night, she would just calmly respond "They're looking for someone."
I didn't think anything of it at the time, but when I told my wife about this recently she thought that was a terrible thing for a mom to say to a little kid.
