Detective Inspector's command creating chaos (8)
I believe the answer is:
disorder
'chaos' is the definition.
(I know that chaos can be written as disorder)
'detective inspector's command' is the wordplay.
'detective inspector's' becomes 'DI's'.
'command' becomes 'order' (order is a kind of command).
'dis'+'order'='DISORDER'
'creating' is the link.
(Other definitions for disorder that I've seen before include "Riders do (anag)" , "Commotion" , "Muddle" , "Confused state" , "Do driers create untidiness?" .)
