Former Facebook chief operating officer Sheryl Sandberg has released a new documentary. ���Screams Before Silence��� explores the October 7 attack on Israel by Hamas. ���I felt like people weren���t paying attention. There wasn���t enough outrage as there should have been,��� Sandberg tells Inside Edition. ���There was even some denial.��� Drawing on interviews from survivors returning to the scene of the attacks, the film focuses on the systematic use of sexual violence by the attackers.
