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.

MTS has outfitted its own officers with body cameras since 2014 but still has no official policies guiding their use or the release of footage. Now, it’s outfitting private contractors with cameras too – but that footage will stay private.

Security officers believed Allen Koka was trespassing when he showed up to his cleaning job at MTS headquarters in 2014. They arrested him in a violent encounter even after a supervisor confirmed he worked there. Among the MTS officers involved were two who have been accused of violence before and remain on the job, a joint investigation by Voice of San Diego and NBC 7 Investigates has found.

SDPD’s use of body-worn cameras has raised a persistent question: How can cameras rebuild public faith if the public can never see the footage? We asked the five candidates for city attorney to share their approach to an overarching body camera policy and to specific videos that become subject to public scrutiny.

As the San Diego Sheriff’s Department prepares to roll out a test run of body cameras, the citizen oversight group that investigates complaints against the department says the sheriff needs to tweak its policies. The group’s No 1 concern: Don’t let deputies review the footage before they write up reports.
