About 60 Minutes Season 54, Episode 10 : Reimagining Police | Supersonic | Caligula's Gardens

Reimagining Police – Scott Pelley reports from Austin, Texas, one of several U.S. cities experimenting with a new way of policing in which trained civilians, such as mental health clinicians, are responding to calls once answered by armed officers. Supersonic – Could commercial supersonic flights make a comeback? Several start-up companies think so, and NASA thinks it can solve one of the problems that grounded supersonic planes the last time around: the "sonic booms" that break windows and rattle nerves. Bill Whitaker reports. Caligula's Gardens – The gardens of the Roman Emperor Caligula have been discovered and excavated, and some of the most remarkable finds are now on display for the first time. How does this affect scholarly efforts to take a new look at the emperor and whether he was as cruel and depraved as he's been made out to be? Anderson Cooper reports from Rome.
