Typical faces of unethical shoplifters unhappy about laws (5)
I believe the answer is:
usual
'typical' is the definition.
(I've seen this before)
'faces of unethical shoplifters unhappy about laws' is the wordplay.
'faces of' says to take the initial letters (I've seen 'face of' mean this).
The initial letters of 'unethical shoplifters unhappy about laws' is 'USUAL'.
(Other definitions for usual that I've seen before include "Drink repeatedly taken" , "regarding customs?" , "Typically done" , "Expected" , "Standard" .)
