US lawman overwhelmed by rage, for example? Possibly (1,4,3)
I believe the answer is:
i dare say
'possibly' is the definition.
(I've seen this before)
'us lawman overwhelmed by rage for example?' is the wordplay.
'us lawman' becomes 'da' (district attorney).
'overwhelmed by' means one lot of letters goes inside another (I've seen this in other clues).
'rage' becomes 'ire' (I've seen this before).
'for example?' becomes 'say' (I've seen this before).
'da' inserted inside 'ire' is 'idare'.
'idare'+'say'='I DARE SAY'
(Other definitions for i dare say that I've seen before include "Maybe" , "One would think" , "Quite possibly" , "It wouldn't surprise me" , "It's very likely!" .)
