A San Francisco State University photojournalism student who witnessed a homicide, and may have even taken photos of the killing, is refusing to talk with police, according to the Chron. The student, whom the paper does not identify, has invoked California’s journalism shield law that protects journalists from revealing information to authorities. The student apparently is staying mum out of fear for his safety and because he doesn’t want to become “a shill” for police. But the student appears to be seriously misguided. The shield law is designed to allow journalists to protect their sources, and should not be used as an excuse by a scared student who witnessed a homicide and is now trying to thwart justice.
