Hearsay With Cathy Lewis

Is there a national surge when it comes to lying on the stand? Scandal after scandal in the past decade, we've seen headlines about many high-profile cases that have struck a damaging blow to our judicial system. Why do people lie under oath? On Thursday's HearSay, we'll talk with the author of "Tangled Webs - How False Statements are Undermining America: From Martha Stewart to Bernie Madoff." James Stewart talks about the consequences surrounding the "perjury epidemic" that's "undercutting the very foundation of our courts: reyling on witnesses to tell the truth." Stewart is a Pulitzer-Prize-winning reporter and also author of "Blind Eye," "Den of Thieves" and other non-fiction works.
