Proof what criminals do infiltrates my address (13)
I believe the answer is:
corroboration
'proof' is the definition.
(corroboration is a kind of proof)
'criminals do infiltrates my address' is the wordplay.
I cannot quite understand how this works, but
'my' could be 'cor' (both are expressions of surprise) and 'cor' is found in the answer.
'address' could be 'oration' (oration is a kind of address) and 'oration' is present in the answer.
The remaining letters 'rob' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'what' is the link.
Can you help me to learn more?
(Other definitions for corroboration that I've seen before include "Confirmation" , "Further proof" .)
