Write a question about the following article.

Back in the lobby , I noticed a sign : ELEVATOR TO OBSERVATION TOWER . Was it possible for us to go up ? Used to Washington , DC , I expected to be challenged , or searched by a bored - yet - hostile security guard , but no one seemed concerned by the sight of me , Mr. McP and Mad Scientist waiting for the elevator on the opposite side of the lobby from where there elevators were for citizens with legitimate business in City Hall .

Question:
What may be the reason why they did n't get searched ?
Choices:
(a). They bribed the guards .
(b). They do n't search people anymore .
(c). They did n't look suspicious .
(d). They were searched at the front door .
