Yesterday Mayor Eric Garcetti announced a plan to outfit thousands of LAPD officers with body cameras by next summer. 

While it would make the LAPD the largest one in the nation to utilize the technology, it's hardly the first department to give it a try. 

In 2012 the small city of Rialto started to use body cameras on police as part of a study into the technology. We talk to the person responsible for the program, Rialto Chief of Police - Tony Farrar.
