“A Love Song for Latasha” is a dreamlike portrait of a vibrant 15-year-old girl whose shooting death sparks the 1992 L.A. Riots. Latasha Harlins would be 45 now. Valerie edited this trailer in collaboration with Netflix. “The film offers a beautiful human element to social injustice,” she says of the project. “My wish is that this film gets viewed by a wide audience.”
