There’s a lot to unpack when it comes to Alex Villanueva’s path to becoming the top cop in Los Angeles County. And that’s exactly what LAist Studios and KPCC do in a new five-part podcast series hosted by Frank Stoltze. Today, we play episode 1 of “Imperfect Paradise: Sheriff.”The show begins with a scene of a very strange press conference: Villanueva is threatening to open a criminal investigation into L.A. Times reporter Alene Tchekmedyian and Stoltze questions the sheriff about it. From there, Stoltze reflects on his time covering policing in L.A. County and explains how Villanueva is the product of a department that has been riddled with scandals for decades: racial profiling, jail violence and deputy gangs.Host: Frank StoltzeMore reading:Your guide to the L.A.
