How did momma and Starr feel as they left the police station why did they feel this way

In Chapter 6, Starr and her mother arrive at the police station, and Starr recounts every moment from the night of the party in detail. She cries. The police officers bring up Khalil's drug dealing and ask if he was in a gang or if they were drinking that evening. Lisa accuses them of trying to make excuses for Khalil's death. Starr and her mother feel victimized by the police and feel they are turning the narrative against Khalil.
