* CriticalResearchFailure: One episode had a murderer using a special round to kill police officers through their vests. It was supposedly a 9mm .30-'06 bullet, despite the 30-'06 round having a diameter of 7.62mm. Also, the supposed "armor-piercing" round was unnecessary, as any rifle round ever made will ignore soft body armor.
** In another episode, a character is found to be using a drug (ephedrine) which they refer to as a performance enhancer (it isn't).
* DieForOurShip: [[spoiler:J.D. Pollack, Lu Simmons]].
* FoeYay: Between Jordan and a [[LesYay female]] serial killer in one episode.
* HarsherInHindsight: In one of the early episodes, Macy and his daughter are trying to have a heart to heart talk, with his daughter asking if he has cancer, and Macy denying it. Miguel Ferrer, the actor who played Garret Macy, died of throat cancer.
