At The Guardian you can find this report on the outcome of a first amendment case involving photographer Arne Svenson who made pictures of his neighbors, without their consent, as they went about their business inside their apartments in a building opposite his own. You can find the series here at Svenson's we site. Bottom line, the photographer's first amendment right to free expression trumps your non-existent right to privacy in your own home. So now you have no expectation of privacy on in public and you have no expectation of privacy in, well, in private! One more reason to make sure you keep your soles clean.
