Threats start off body searches (5)
I believe the answer is:
risks
'threats' is the definition.
The definition and answer can be both states of affairs as well as being plural nouns.

Can you help me to learn more?
(Other definitions for risks that I've seen before include "Puts in jeopardy" , "Hazards, dangers" , "Perils" , "Exposes to danger" , "Sources of dangers" .)
