When Malloy and Reed bring in a rape suspect, while he's being processed, Malloy asks what they should do with the suspect's car, which was still on the side of the road. Sgt. MacDonald tells them to leave it up on the road, that the suspect may be driving it home.
Normally, the car would be hauled in and forensics would go over the car for more evidence, since there was sufficient probable cause already to make an arrest on suspicion.
Rape Suspect: (after Malloy finds a knife in his trunk) That's mine. I use it when I go fishing. Is there any law against that?
Malloy: If what you're fishing for is young and female, the answer is yes.
