The thing is, the right to privacy is a very contraversial one, and I really don't like the idea that people consider their privacy to be akin to free speech and practice of religion. I am protected from unreasonable search and seizure and the like... not from people know my secrets. If I hide it, the gov't can't simply explore my personal affairs. If I don't shut the window however, it's not their job to avert their eyes.
