Digital devices – phones, computers, tablets – have become integral to our daily lives. And they have become tools for criminals. What’s found on a suspect’s digital device could make or break a case. Ask Detective Robert Weaver, who specializes in digital forensics. He has uncovered troves of damning evidence by sifting through digital data while working at the department that once employed our twin detectives, Dan and Dave. Today, Detective Robert talks about how your phone knows more than you think, when and how police can seize devices, and how digital detectives have cracked cases wide open. Oh, and they talk about Artificial Intelligence, too!
