Los Angeles Mayor Eric Garcetti announced Tuesday that the city would purchase 7,000 body cameras for police officers, reports the Los Angeles Times.

The introduction of body cameras is part of an effort to increase transparency. Body cameras have become a focus since the killing of Michael Brown by now-former Ferguson, Mo., Police Officer Darren Wilson.

Garcetti told reporters in a news conference that body cameras "are not a panacea, but they are a critical part of the formula. They're a great step forward. The trust between a community and its police department can be eroded in a single moment. Trust is built on transparency."
