Deputy's not so sensitive about arresting women (6,3)
I believe the answer is:
number two
'deputy's' is the definition.
(I've seen this before)
'not so sensitive about arresting women' is the wordplay.
'not so sensitive' becomes 'number' (I've seen this before).
'about arresting women' becomes 'two' (I can't explain this - if you can you should give a lot more credence to this answer).
'number'+'two'='NUMBER TWO'
Can you help me to learn more?
(Other definitions for number two that I've seen before include "Dump" , "Second in command" , "vice" , "Assistant" , "deputy" .)
