As I understand it, criminology is the study of the effect of crime on individuals and society. Not an area I know about.
But forensic science is very relevant in understanding crimes in the first place. Someone needs to take samples from a crime scene (avoiding contamination) and then someone needs to process the DNA collected. Someone needs to process the samples to understand what drugs were being used/sold.
