Journalist Cyrus Farivar knows a thing or two about surveillance. While reporting for Ars Technica, Farivar got the entire license plate reader dataset from the Oakland Police Department -- that’s all of the license plate scans they recorded and saved -- from December 2010 to May 2014. He says Oakland has no official policy for how long they keep all of that information. And, he says, it’s not the only problematic surveillance technique being used in the city, or across the state. Farivar came into our studios to talk about his reporting with KALW’s Sandhya Dirks.
