Just organised huge riots (9)
I believe the answer is:
righteous
'just' is the definition.
(associated in meaning)
'organised huge riots' is the wordplay.
'organised' is an anagram indicator.
'huge'+'riots'='hugeriots'
'hugeriots' with letters rearranged gives 'RIGHTEOUS'.
(Other definitions for righteous that I've seen before include "law-abiding" , "Morally justified" , "Virtuous, free from sin or guilt" , "Moral - virtuous" , "Good!" .)
