the last 2 criminologists CU Boulder soc dept hired got their PhDs in Criminology and Criminal Justice. This is something that would have never happened in sociology two decades ago. I am not saying it is a bona fide trend but it speaks to the inane legitimacy/illegitimacy debate on this thread.
it is still more common for C&CJ programs to hire scholars with degrees in sociology than the converse, though. but this has become a lot less common in the last 10 years or so.
