Lawyer content to leave burglars' fingerprints (4)
I believe the answer is:
dabs
'fingerprints' is the definition.
(I've seen this before)
'lawyer content to leave burglars'' is the wordplay.
'lawyer' becomes 'da' (abbreviation for District Attorney).
'content to leave' suggests removing the centre (the contents of the word are removed).
'burglars' with its middle removed is 'bs'.
'da'+'bs'='DABS'
(Other definitions for dabs that I've seen before include "fingerprint" , "Small quantities of liquid" , "Fingerprints (colloq.)" , "Fingerprints (slang)" , "'Pats at, with a cloth, say (4)'" .)
