Gets ball, perhaps, for policemen (3,4)
I believe the answer is:
cop shop
'gets' is the definition.
I know nothing about this answer so I can't judge whether this works.
'ball perhaps for policemen' is the wordplay.
'ball perhaps' becomes 'hop' (informal dance event. I am not sure about the 'perhaps' bit.).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'policemen' becomes 'cops' (cop is a kind of policeman).
'hop' put after 'cops' is 'COP-SHOP'.
Can you help me to learn more?
(Other definitions for cop shop that I've seen before include "office investigating crime" , "Nick" , "Police station (slang)" , "'Police station (3,4)'" .)
