Media Appearances

Ms. Napoli is a legal and current affairs news commentator for numerous national media outlets and providers her insight on a variety of issues.

With appearances on Court TV, Law and Crime Network Live, Dr. Oz, Newsmax, Rolling Stone, New York City’s WPIX-TV 11 News, TRT World and others, she provides well-reasoned views on topics from “biased male views toward female victims” in the case of the Playboy Model Murder case; “extreme, wanton criminal negligence” in the case of the Breonna Taylor case; the “unwarranted, ingrained notion of race discrimination” in the George Floyd case; and the need for victims of sexual assault to take their power back by filing civil lawsuits, as in the case of Charity Carson.

Additional cases she has assessed include the Jealous Lover Murder Trial — where she provided legal analysis on the multiple problems involved with a juror improperly communicating with her parents; the Teen Charged with Killing Two Kenosha Rioters, where she explained how it is up to a jury to decide whether it was murder or self-defense by Kyle Rittenhouse; The Tammy Daybell Effect on Chad Daybell’s Case, where she assessed the Courtroom vs. the Court of Public Opinion in Tammy Daybell’s death; and the responsibility of attorneys during COVID-19 when courts are physically closed.
