Al, playing in a cop role? (6)

I believe the answer is:

pacino

I'm a little stuck... Click here to teach me more about this clue!

'al playing' is the definition.
I know nothing about this answer so I can't tell whether this works.

'in a cop role?' is the wordplay.
'in a cop' anagrams to 'PACINO'.
However, I'm unsure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for pacino that I've seen before include "Al --, actor" , "Hollywood star" .)

I've seen this clue in the Evening Standard.
