El Cajon Police Chief Jeff Davis has said his office, and the San Diego County district attorney’s office, will both investigate a shooting that took place Tuesday in which a black man killed by police. As that process plays out, here’s what we know about when an officer can legally shoot someone, how the DA approaches the release of shooting videos and how San Diego officers who’ve killed people have been handled in previous cases.

In a sworn deposition obtained by Voice of San Diego, San Diego Police Officer Neal Browder said he did not face any internal discipline or reprimand following an April 2015 incident in which he shot and killed an unarmed, mentally ill man. Browder also said that he was never interviewed by anyone in the district attorney’s office, or anyone in internal affairs, although both offices investigated the incident.

Police Chief Shelley Zimmerman and others at one point argued that it’d be impossible to assemble an unbiased jury if video of a disputed police shooting was made public. Now that the video has been released, the city says the potential jury pool is fine – and is fighting the victim’s family’s attempt to move the trial.

District Attorney Bonnie Dumanis released surveillance video and other carefully curated pieces of evidence to back her perspective that Officer Neal Browder’s shooting of Fridoon Rawshan Nehad in a Midway alleyway was justified. Similar news conferences could become commonplace from now on in disputed police shootings.

District Attorney Bonnie Dumanis on Tuesday released private surveillance footage of the police shooting that claimed the life of Fridoon Rawshan Nehad in late April in the city’s Midway district. Dumanis also released several other pieces of evidence that she said backed up her decision not to charge the officer involved in the shooting, but declined to release other documents, including the officer’s statements following the incident.
