Arranged offensive act using subject-matter from Scorsese film (9,5)
I believe the answer is:
organised crime
'subject-matter from scorsese film' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'arranged offensive act' is the wordplay.
'arranged' becomes 'organised' (organising is a kind of arranging).
'offensive act' becomes 'crime' (crime is a kind of act. I am not sure about the 'offensive' bit.).
'organised'+'crime'='ORGANISED CRIME'
'using' is the link.
Can you help me to learn more?
(Other definitions for organised crime that I've seen before include "taking things in systematic way?" , "Mafia?" .)
