"Traditional license plate readers were developed in the 1950s and 60s," says this week's guest, Garrett Langley of Flock Safety. "But you can go into Flock and say I'm looking for a black Sedan with after-market tires and a dent on the left corner, and we will find that car."

Former Atlanta Mayor Kasim Reed and former Philly Mayor Michael Nutter, along with Citizen Co-founder Larry Platt, chat with Langley about his innovative and cost-saving approach to public safety, which made national headlines last year by promptly apprehending a would-be Trump assassin and an Atlanta mass shooter. After being the victim of a robbery in his own neighborhood, Langley reimagined vehicle surveillance and built a company that operates alongside thousands of law enforcement agencies across the country.

"I love citizen entrepreneurs who are in the civic problem-solving business," Platt told the mayors. "That's who this guy is."
