Paris, April 4, 2017, 4:00 am. A Malian Muslim named Kobili Traore breaks into the apartment of one of his neighbors, Sarah Halimi. He knows she is a Jew. In the past, He has repeatedly uttered anti-Semitic insults at her. Halimi and her family had filed complaints and asked the police to intervene. Each time, the police respond that Traore has not committed a criminal act, and that they did not want to be accused of anti-Muslim prejudice.
That day, Traore decides to go from words to deeds. He beats Halimi violently. He tortures her. She screams. Neighbors call the police. This time the police do something -- but not enough.
When they arrive at Halimi's door, they hear Traore shouting Allahu Akbar, and shaytan ("demon"). In a jarring breach of duty, they decide to run away. They walk out of the building and call for reinforcements.
