Balanced my crimes out over time (9)
I believe the answer is:
symmetric
'balanced' is the definition.
(thesaurus)
'my crimes out over time' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'over' is an insertion indicator.
'time' becomes 't'.
'my'+'crimes'='mycrimes'
'mycrimes' is an anagram of 'symmeric'.
'symmeric' enclosing 't' is 'SYMMETRIC'.
(Other definitions for symmetric that I've seen before include "Equally balanced" , "Regular" .)
