One who studies legal violations and their perpetrators (13)

I believe the answer is:

criminologist

(Other definitions for criminologist that I've seen before include "One studying felons" , "Low-life expert" , "Expert in breaking the law?" , "Scientist studying offenders" , "One studying law-breakers" .)

I've seen this clue in The Times.
