SF District Attorney

Policy

Independent Investigations Bureau

IIB is an independent unit within the SFDA’s Office, which reports directly to the District Attorney, committed to ensuring law enforcement accountability by conducting independent investigations, and where warranted, criminally prosecuting officers who violate the law.

IIB's Main Responsibilities

1. Investigate and review all officer-involved shootings and in-custody deaths.

2. Investigate and review all other excessive use of force cases.

Contact Us

IIB responds to reports from the public and other agencies. Attorneys and investigators work together on these matters to conduct diligent, independent investigations of all credible allegations. Whether by referral or through the on-call process, IIB’s approach is designed to ensure that professional, thorough, and impartial investigations are conducted.

IIB may be reached by e-mail at SFDA-IIB@sfgov.org or telephone at (415) 581-9805.

Independence of the Unit

  • IIB works autonomously and independently of every other unit within the District Attorney’s Office
  • Exclusively works on police use of force cases and post-conviction claims of innocence
  • All final reports written by IIB are submitted to the California Department of Justice and posted on the office’s website
  • The press is also notified of every decision
  • IIB reports to the District Attorney

Leadership

IIB is led by Lateef Gray, who has dedicated his entire legal career to representing the underserved and fighting for individuals’ civil rights. He joined the District Attorney’s Office this year after five years as a trial attorney prosecuting civil rights violations committed by law enforcement including cases involving police brutality.

IIB Dashboards

Promoting accountability in law enforcement, and preventing unlawful conduct that harms the community, requires transparency. For too long in the United States, officer-involved shootings, in-custody deaths, and use-of-force incidents have been shrouded in secrecy. As the lead criminal investigator of these incidents in the City and County of San Francisco, the Internal Investigations Bureau documents and tracks every officer-involved shooting and in-custody death. The IIB Dashboards provide near real time data, broken down by victim demographics and agency.

While the San Francisco District Attorney’s Office has been collecting data on officer-involved shootings and in-custody deaths since the late 1990s, the data from before 2011 may be incomplete. All incidents since 2011 are represented in the dashboards.

In part stemming from the Blue Ribbon Panel on Transparency, Accountability, and Fairness in Law Enforcement’s recommendations, IIB was formed in late 2016. On April 10, 2019, IIB and SFPD executed a Memorandum of Understanding regarding the investigation of officer-involved shootings, in-custody deaths, and uses of force resulting in serious bodily injury. Of note, 2019 is the first year on record that has not had any fatal police shootings as of the end of October. SFDA has prosecuted over 20 officers for police misconduct.
