The difference between secrecy and privacy is the key here. Emphasize that. People think they have nothing to hide (implying secrecy or guilt), but they'll admit that there are things they want to keep to themselves. There was a speaker on stage (sorry I forget the source) that asked an audience member up. The speaker asked the individual to read aloud her credit card number to the rest of the audience. She refused. He took it a step further -- he asked her to remove her clothes on stage. Again, she refused. Was she hiding something? Was she wielding a dangerous weapon under her clothes? Or was she reacting like most people presumably would by refusing to undress?
