This week, for the first time, 75 San Diego police officers will be wearing body cameras either on the chest or lapel.

 Officers are required to record every so-called "enforcement contact."

"No officer is going to tamper with that. By using and how we dock it into the station, and how the film is uploaded and downloaded, it cannot be tampered with," said San Diego Police Department Chief Shelley Zimmerman.

Zimmerman said body cameras will help build community trust.

To address concerns over racial profiling, Zimmerman wants cameras to first be used in three of the city's most diverse communities: the department's Central, Southeastern and Mid-City divisions.

"This holds the officer accountable, but it also holds the public accountable too," Zimmerman said.

She said other departments using body cameras have reported an 80 percent drop in complaints against officers.

Attorney Gene Iredale agrees that it is a win-win situation.

"It protects citizens from brutality and cowboy tactics. It also protects police from unfounded accusations," said Iredale.

Iredale said the policy must be clear.

Regarding privacy, the department's policy states: "Private citizens do not have a reasonable expectation of privacy when talking with officers during official duties … even when in a private residence … Therefore, officers are not required to give notice they're recording."
