Why do we have to be searched at the airport?
user
There are several reasons.  One is that there’s a concern that terrorists might be trying to hide weapons or other things in your luggage, so the airport authorities want to be able to inspect and detect these if they’re in your luggage.  Another reason is that in some cases passengers are trying to smuggle items through security to avoid paying the fees, so the security staff want to be able to inspect them, in order to make sure these things are bought, or the fees are paid.  And finally, there’s a concern that many passengers are bringing things like illegal drugs or other things that they don’t want others to know about, but for which the airport staff have a search warrant, so they can also perform a search if they have this permission.
