(NewsNation Now) — The ruling that seemed to come out of nowhere today, throwing-out Bill Cosby’s conviction on three counts of sexual assault and sending him home a free man, boils down to one simple point: the prosecutor used Cosby’s own words against him, after the previous prosecutor promised Cosby he wouldn’t.

And so after three years in a maximum-security prison near Philadelphia, the entertainer once considered as wholesome as Jello pudding stepped into the sunshine looking every bit his 83 years and not saying a word, even while surrounded by jubilant lawyers.

An expert panel explains the ruling, including: Tom Mesereau, a criminal defense attorney whose former clients include Michael Jackson, Robert Blake and Bill Cosby; Tanya Acker. a former litigator who now appears on TV’s Hot Bench; and Lisa Bloom, a lawyer and legal commentator who represented one of Cosby’s accusers in a defamation case.

And later, comedian Larry Wilmore looks at the history of Cosby’s case and the importance of the constitutional protections which ultimately led to his release.
