Revealing article about state of Raleigh’s carelessness (10)
I believe the answer is:
negligence
'carelessness' is the definition.
(I know that carelessness can be written as negligence)
'revealing article about state of raleigh's' is the wordplay.
'revealing article' becomes 'negligee' (revealing article of clothing).
'about' is an insertion indicator.
'state of raleigh' becomes 'NC' (Raleigh is the capital of North Carolina).
'negligee' going around 'nc' is 'NEGLIGENCE'.
(Other definitions for negligence that I've seen before include "Being far from careful" , "Disregard" , "dereliction of duty" , "Carelessness" .)
