My housemate's car was stolen in Atlanta, and because of Flock the police were able to get it and return it the same day he reported it missing. He was even able to get to work on time.
Sometimes the police just get lucky...
More information: the car was stolen at night, and my housemate only saw it was gone in the morning. The police were able to return it that same morning and he was able to go to work.
We had a ring camera pointed right at the car which was parked on the street. Ring didn't record its theft as an "event" so there was no footage to work with.
My housemate also had a camera in his car which records while driving. There was footage of the thief just taking the car for a joyride. My housemate did not press charges.
