The Justice Project: Crime Labs Need Independence and Robust Oversight to Ensure Justice

Blog post here. Excerpt:

'San Francisco’s top public defender, Jeff Adachi, recently called for the city’s crime lab to become independent of the police department. This announcement comes on the heels of a series of scandals in the San Francisco Police Department’s forensic laboratory initiated by the discovery that a criminalist was stealing cocaine from evidence storage facilities. What initially seemed to be a problem with one unethical employee has led to the unearthing of myriad problems within the lab, including two cases of tainted DNA samples. Moreover, a troubling audit was released showing an improper maintenance of chain of custody of evidence, inadequate record keeping, and a lack of cleanliness in the overall facility. Multiple legal challenges raised in the aftermath of the scandal, including a murder case, have pointed to the possibility that police and prosecutors withheld vital information about the drug thefts from defendants’ attorneys.

Adachi is right to push for an independent crime lab. The majority of publicly operated crime labs are part of a law enforcement agency. As a result, crime lab employees may come to see themselves as part of a crime fighting team, rather than objective agents of science. Given that many forensic examinations involve subjective interpretations of data, the risk for bias is greater when the lab is structurally part of law enforcement. Independent crime labs help to ensure that analysts operate maintain an impartial environment to ensure accurate, unbiased and reliable testing. The National Academies of Science recognized these concerns when they recently recommended that laboratories become independent of law enforcement agencies.'
