Reference facsimile fooling Yard initially, ensnaring corrupt police (4,4)

'reference facsimile' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'fooling yard initially ensnaring corrupt police' is the wordplay.
'initially' says to take the initial letters.
'ensnaring' indicates putting letters inside.
'corrupt' is an anagram indicator (a corrupted form).
The first letters of 'fooling yard' is 'fy'.
'police' anagrammed gives 'ilecop'.
'fy' placed around 'ilecop' is 'FILE COPY'.

Can you help me to learn more?
