Severe restrictions result in shoot-out? (9)
I believe the answer is:
penalties
'result in shoot-out?' is the definition.
(as in a penalty shoot-out)
'severe restrictions' is the wordplay.
'severe' becomes 'penal'.
'restrictions' becomes 'ties'.
'penal'+'ties'='PENALTIES'
(Other definitions for penalties that I've seen before include "Punitive impositions in Palestine" , "Fines or forfeitures in Palestine" , "parking fines" .)
