Continuity mistake: Benson visits Stabler at his home to confronts him about the FBI detail he has ordered to protect her. They talk outside and then Benson is seen walking away. The next shot shows a side shot of Benson approaching him again in silence but mouthing words to him. (00:49:00)
Revealing mistake: When Amanda and Fin are in Atlanta following up on their rape case, they walk past several cars with visible Georgia license plates mounted on the front. Georgia is a rear plate-only state and wouldn't have had license plates mounted on the front of the cars, as shown here. (00:13:30 - 00:16:20)
Character mistake: The fetus' blood type was AB and the mother had a known type of A. So Dr. Huang said the Father had to be type B which is not completely true. The father could also be type AB as long as he had a single chromosomal copy of the B allele, which any doctor would know. During meiosis only half your genetic DNA is passed on to the offspring.
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.
Deliberate mistake: When James is shot on the courthouse steps, the crowd of reporters that has gathered quickly scatters to escape the gunfire. One of them is a woman in a black windbreaker holding a camera. The camera cuts away briefly and then back to the crowd - you see the exact same people, including the woman in black running in the exact opposite direction as before. The footage was apparently mirrored and repeated for the second shot of the fleeing crowd.
Continuity mistake: In the scene where Detective Munch visits the hospital room of a young comatose girl for the first time, the girl's left arm is alongside her body above the top sheet. As Munch approaches the bed, her arm is below the top sheet. When Munch visits the still-comatose girl a second time in the last scene of the episode, in the foreground as he is entering the room the girl's head is turned, facing her right. As he pauses to watch her, in the next shot she is now facing upright towards the ceiling. In this same shot, the purportedly still-comatose girl slightly moves her head and lips as if swallowing.
Continuity mistake: When Benson and Stabler are interviewing Virginia at the end of the episode, when she admits to committing the crime, she breaks down into tears and her face turns red. The next shot is from over her shoulder, and her expression is normal. In the very next shot, from the front, her face is flushed and tears again.
