Continuity mistake: Claudette and Dutch are questioning a man in a leather jacket about his involvement in a meth lab. Claudette passes the man a photo, he doesn't recognise the girl, tosses it back across the table and Claudette reaches for it with her right hand. The shot changes and now the photo is in Claudette's left hand as she sets it down.
Continuity mistake: Aceveda and Vic are interrogating a man about the 'Narco Corrido' murders. Aceveda pushes the man into the corner of the room and begins to kick him. He get about six good kicks in before Vic diffuses the situation. After, Aceveda storms out of The Barn in anger, and Vic views the recording from the interrogation room. The footage is inconsistent as to what transpired earlier, in fact it is an entirely different take. Aceveda only manages about two kicks before Vic says "Enough, enough" - this and the rest of the dialogue is also conflicting.
Continuity mistake: As Vic, Lem and Ronnie are talking to the two men at the table, they restrain the men (seemingly only Juan is handcuffed, with his arms behind him - Ronnie seems to only pin one of the other men's arms behind him). After Vic, Lem and Ronnie walk away, at no point do they undo at least Juan's handcuffs, but immediately the two men are rubbing their freed hands.
Continuity mistake: During the fight scene between Shane and Tavon, the stereo speakers get knocked off the shelf. After they crash into the wall, and a picture falls off, they tackle each other and fall to the ground. As they tackle each other, we get a shot of the floor at the bottom of the shelf and there are no speakers there. Later when Mara comes into the room, as she picks up the iron, the speakers are visible in the background.
