Privacy is not a function of whether or not you have anything to hide. I get sick of hearing that. The last time I had a discussion with one of those “If you have nothing to hide, you have nothing to worry about” people, I told him if the police ever show up at my house and ask to search it without a warrant, I’m going to tell them, no, but give them his address and say “This guy says he has nothing to hide and doesn’t see a need for a fourth or fifth amendment. Go search his house without a warrant. I’m sure he’ll let you.”
