Lawyer discarded shot (6)
I believe the answer is:
dashed
'shot' is the definition.
('dash' can be a synonym of 'shoot')
'lawyer discarded' is the wordplay.
'lawyer' becomes 'da' (D.A. is an example).
'discarded' becomes 'shed' (I've seen this before).
'da'+'shed'='DASHED'
(Other definitions for dashed that I've seen before include "Thrown down as hopes sometimes are" , "Cast down as hopes may be" , "Ran quickly, rushed" , "Darted headlong" , "hurled at" .)
