CARRIE JOHNSON, BYLINE: Twenty-three states and the District of Columbia already record questioning of people in police custody. But federal law enforcement had long refused to take that step until this month. Mark Giuliano is the deputy director of the FBI - the highest ranking agent in the bureau.
MARK GIULIANO: So it used to be that we actually had to get permission to record. And now we're at the point where we actually have to get authority not to record.
JOHNSON: The world has changed, and Giuliano says the FBI is starting to change along with it.
This January, after the driest calendar year in California history, Gov. Jerry Brown declared a drought emergency. He called on residents to reduce their water intake by 20 percent.
But downtown Los Angeles doesn't looklike a city devastated by the state's worst drought in decades. The city is green with landscaping, and fountains are running. People still water their lawns, wash their cars and fill their pools.
