The department is handing over the criminal case to an independent body and is now seeking an additional investigation into the department's actions, including those of the chief.
"SFPD Chief William Scott showed everyone in the SFPD, and all San Franciscans, what his character consists of," the police union said in a statement. "It was a pathetic, deceitful and shameful display of self-preservation, finger pointing, and political kowtowing."
A police department spokesperson said Saturday the Department of Police Accountability will conduct the investigation to look into how the case has been handled by all levels of the department. "Chief Scott has made it abundantly clear that transparency and accountability are paramount in this criminal investigation," the spokesperson wrote in a statement.
Earlier this month, police officers used a sledge hammer to bust open the front gate of San Francisco journalist Bryan Carmody's home. Scott justified the action this week and said he believed Carmody conspired with someone in the department to obtain a police report about the death of former public defender Jeff Adachi.
