Think about criminal model (11)
I believe the answer is:
contemplate
'think about' is the definition.
(to contemplate something is to think about it)
'criminal model' is the wordplay.
'criminal' becomes 'con' (abbreviation for 'convict').
'model' becomes 'template' (template is a kind of model).
'con'+'template'='CONTEMPLATE'
(Other definitions for contemplate that I've seen before include "Intend" , "Think seriously" , "Look at thoughtfully" , "Ponder" , "Consider" .)
