bullshit.  the real reason "nothing to hide" is invalid is that it refuses to recognize that we don't cede <i>all</i> moral responsibility to the government. thus it usually comes out of the mouth of people who <i>do</i> think the government should ultimately be responsible for morality.  this means that all moral decisions have legal penalties.  morality at the end of a gun should be reserved for things we actually agree on.  things like rape, murder, theft, fraud, reckless endangerment etc.<p><i>puts on libertarian helmet</i>:<p>"There's no way to rule innocent men. The only power government has is the power to crack down on criminals. Well, when there aren't enough criminals, one makes them. One declares so many things to be a crime that it becomes impossible for men to live without breaking laws." -Rand<p>I guarantee that all of us are breaking laws of some sort everyday.  even if it's just the speed limit.
