Pillaging (7)
I believe the answer is:
looting
'pillaging' is the definition.
(I know that pillaging can be written as looting)
This is the entire clue.
(Other definitions for looting that I've seen before include "Stealing during a disturbance" , "pillage" , "Wartime stealing" , "Sacking" , "Stealing in times of unrest" .)
