Cade Metz reports:
When the Chula Vista police receive a 911 call, they can dispatch a flying drone with the press of a button.
On a recent afternoon, from a launchpad on the roof of the Chula Vista Police Department, they sent a drone across the city to a crowded parking lot where a young man was asleep in the front seat of a stolen car with drug paraphernalia on his lap.
