Overly broad daughter is cutting finger (14)
I believe the answer is:
indiscriminate
'overly broad' is the definition.
'daughter is cutting finger' is the wordplay.
'daughter' becomes 'dis' (I've seen this in other clues).
'is cutting' indicates putting letters inside (some letters cut their way into a word).
'finger' becomes 'incriminate' (both can mean to identify someone as a criminal).
'dis' going within 'incriminate' is 'INDISCRIMINATE'.
(Other definitions for indiscriminate that I've seen before include "Done at random" , "Uncritical" , "Sweeping" , "purposeless" , "Acting at random" .)
