By now, we all know that Lance Armstrong will admit to doping on Thursday's much-anticipated interview with Oprah Winfrey. But the segment has already spurred its own questions: Will he apologize? Does he explain why? Will he admit to blackmailing anyone or threatening people around him? And does Armstrong, as Charlie Rose so desperately wanted to know on CBS Tuesday morning, appear contrite?
