Get into trouble with the police (3,2)
I believe the answer is:
cop it
'get into trouble' is the definition.
(to cop it is to receive punishment)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for cop it that I've seen before include "Be punished" , ""get in loads of trouble!"" , "Get into trouble; be killed" , "Get it in the neck" , "Suffer the consequences!" .)
