Enlightened detectives subjected to insults, perhaps (9)

I believe the answer is:

disabused

'enlightened' is the definition.
(thesaurus)

'detectives subjected to insults perhaps' is the wordplay.
'detectives' becomes 'dis' (Detective Inspectors, DIs).
'subjected to insults perhaps' becomes 'abused' (abuse can mean insults or verbal attacks).
'dis'+'abused'='DISABUSED'

I've seen this clue in The Times.
