Revealing mistake: In the scene where Detective Munch visits the hospital room of a young comatose girl for the first time, we see that the girl's left arm is alongside her body above the top sheet. As Munch approaches the bed, we now see that her arm is below the top sheet. When Munch visits the still-comatose girl a second time in the last scene of the episode, we can see in the foreground as he is entering the room that the girl's head is turned, facing her right. As he pauses to watch her, we then see in the next shot that she is now facing upright towards the ceiling. In this same shot, you will also notice the purportedly still-comatose girl slightly move her head and lips as if swallowing.
Continuity mistake: When Stabler steps out to confront Tarzi, there is a long, brown brick wall to Tarzi's right. Tarzi then turns and runs across the street and is followed by Fin. Munch steps out and yells "halt!" There is another shot of Tarzi and he stops again. Right before he is tackled by Fin, behind him, to his right, is the same brick wall as before even though he crossed the street and ran down the block.
