San Francisco District Attorney Kamala Harris said Friday her office had until recently been in the dark about problems in the city's crime lab that the police department had known about. An evidence-tampering scandal that erupted in March and led to the closure of the lab's narcotics unit has prompted prosecutors to drop about 550 narcotics cases. Harris said she is working on legislation to make crime lab evidence-tampering by a civilian employee of a police department an automatic felony punishable by state prison.
