One way to police love and play (4,9)
I believe the answer is:
zero tolerance
'one way to police' is the definition.
I can't judge whether this definition defines the answer.
'love and play' is the wordplay.
'love' becomes 'zero' (love is zero in tennis).
'and' is a charade indicator (letters next to each other).
'play' becomes 'tolerance' (both can mean room for movement in engineering).
'zero'+'tolerance'='ZERO TOLERANCE'
Can you help me to learn more?
(Other definitions for zero tolerance that I've seen before include "Strict police policy" , "not putting up with anything wicked?" , "Strict treatment" , "legal issue?" , "Uncompromising approach" .)
