One way to police love and play (4,9)

I believe the answer is:

zero tolerance

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

'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" .)

I've seen this clue in The Sunday Times and The Times.
