I don't know. Why should people have their shits recorded or their sexual relations, or their weird fetishes. Power may corrupt but you have to be reasonable. Government officials are also citizens, just working for the government. They still have all the rights you have. If anything, for example, the President has more eyes on him just because of his position anyway.
While I agree about shits and sexual fetishes there are lots of times I don't agree with this. Like the right to speak your own opinion. I remember being at an antiwar protest and having a line of cops dressed in full riot gear with tear gas canister shooting rifles slung over their shoulders calling us faggots and un-American and all sorts of other colorful pejoratives. Now it seems to me that if they weren't dressed in the riot gear or acting in an official capacity they would have had the right to say those things. Sort of like with the Sarah Palin email fiasco. She doesn't have a right to conduct official business in a private manner. The line between person and role is very blurred and it's hard to really separate the two. I don't care about the sex life of someone in Minerals Management Services unless it becomes obvious that their sex life is being fed by the corporations he's trying to regulate.
