Suspicionless searches, or a "Terry stop" is when a law enforcement officer stops any member of the public and performs a search of their person without any probable cause or reason to search them.

How the need to ensure public safety might justify suspicionless searches would certainly be in an area of high crime. Individuals can be anybody and can have anything on them. Law enforcement as a result will tend to scrutinize or to closely watch the area and anybody in it.
