- Harmful to Minors: Mary Beth tries to invoke this on her son Harvey Jr by taking him to watch the examination of a child's body who died from a gun.
- I Just Shot Marvin in the Face: Cagney and Lacey discover their suspect was accidentally shot with the gun which he and his wife had purchased illegally in order to protect themselves from intruders.
- Reckless Gun Usage: Mary Beth finding her son aiming her revolver at his friend (for thinking his mom was just a meter maid instead of an actual cop). Even after taking the gun from her son and punishing him for it, she still worries about it.
