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.
Character mistake: At the end of the episode, Abby Carmichael says that professor Rousseau will be convicted of three class-A felonies, with a term of a year each. According to NY state laws, three class-A felonies would lead to the death penalty; Abby meant to say three class-A misdemeanors.
