The End - S11-E15

Factual error: The badge the ATF Special Agent is displaying on his suit jacket is wrong. It's the wrong shape and style of an actual ATF Badge. (00:02:57)

Snag.1

Officer Down - S1-E4

Factual error: Danny and Jackie Curatola are with ESU to make an arrest at a garage. They are behind cover with their weapons drawn. Although there is no suspect shooting at them, both Danny and Jackie have their fingers on the trigger, which is against police training unless you are going to engage a subject by shooting your weapon. The ESU officer right next to them does not have his finger on the trigger. (00:38:04)

Your Six - S8-E20

Factual error: Danny shoots Frank's revolver, and as he continues to shoot, you hear the sound of a casing hitting the floor, which shouldn't happen since it's a revolver being fired. (00:11:46)
