Factual error: The FBI agents are searching a house with their weapons drawn. Each agent is going through the house with their fingers on the trigger. At one point, one agent has her finger on the trigger while her partner is in front of her as they go down some stairs. The correct officer safety practice is to have your trigger finger off the trigger and along the slide of the weapon until you are engaging a suspect and need to fire your weapon.

Character mistake: The FBI team responds to a murder crime scene. The victim is lying face down in the bed with blood everywhere. The team leader takes the victim's wrist with his bare ungloved hand. A trained FBI agent would never touch a murder victim without gloves - one to protect himself and two not to contaminate the crime scene. (00:10:00)
Continuity mistake: While the Agents are reviewing the courthouse security footage, they zoom in on the unsub's license plate number "28K-XK8" on the video feed. Barnes states aloud that it's "28K-XQ8" and Remy asks which employee drives a vehicle with that plate number, then the Courthouse Vehicle Directory shows "28K-XQ8" as the unsub's license plate number.

Visible crew/equipment: At the courthouse, while the Agents are in the room with the corpse, Hurstview stands behind an overturned potted plant. After Hurstview opens Skip's safe, just as Barnes and Long exit the room Hurstview moves his foot, and the actor's green tape mark is visible on the carpet at his feet. (00:20:00)
