A new documentary helped prompt California legislators into signing a new bill on Sunday that would allow women who are being tried or are already convicted and incarcerated for killing their abusers to bring evidence of abuse into court.

That documentary, “Sin by Silence” by Investigation Discovery, tells the story of spousal abuse and domestic violence and how the California justice system handles those types of cases. The film also dives into the history of Convicted Women Against Abuse, an organization created by Brenda Clubine, who spent 11 years in prison for the murder of her husband before abuse evidence revealed she acted in self-defense.

Host Jamila Bey spoke with documentary creator Olivia Klaus and Clubine about the film and the new law.
