Two young black men hit on an incredibly young and pale Cynthia Nixon, so she shoots them both dead. It' not unlike how her Sex and the City character would have responded, if you replace "shoots them" with "allows them to have sex with her."
Her character later claims that the pair was about to assault her, and Nixon spends the rest of the episode defending her trigger-happy reaction.
Ripped from the headlines?
The entire incident occurred almost verbatim in 1984, when New York City was suffering its highest crime rate in history, and a guy named Bernhard Goetz, like Nixon, shot two young black men on a subway. That went over about as well as you would imagine.
This L&O episode also features a reality-based victims' rights group consisting of black men who swagger into the courtroom and re-enact the crime, which results in a riot. (This was early in the series, when witnesses could crack wise on the stand and the court would erupt in laughter. The legal half of Law & Order was, after all, a Night Court spin-off.)
Worth watching uncomfortably?
To complete the Sex and the City circle, there's a wonderful scene in which two uniformed cops are searching Nixon's apartment and they discover some books on how to achieve orgasm. They're yukking it up just as Nixon walks in. She gives them a "sad bear" look like Jack Lemmon in Glengarry Glen Ross.
Miranda would have turned their penises to ash with the power of her mind, and used them to garnish her Cosmo. So yeah, there' a delightful awkward pleasure in this one.
