There are plenty of reasons to not want the police to have access to your address, see Darrow v Kuehnlein http://blogs.riverfronttimes.com/dailyrft/2013/06/james_kuehnlein_velda_police_assault.php http://www.examiner.com/article/the-brett-darrow-case-a-hero-our-time http://www.thenewspaper.com/news/19/1988.asp The police staked out his home, they harassed his neighbors, they encouraged other cops to do the same; all because he dared to stand up for his rights. So, no 'legal consequences', but enough 'extra-legal' ones to make me want to remain a very private person. If that's not enough reason, ask the next police officer who's questioning you on some matter what his home address is, where his wife and children are when he's at work. If, in the unfortunate circumstance I have to defend myself, then so what? It's not like a self defense shooting becomes a bad shooting based merely upon the absence of a piece of paper. Identification will be made, one way or another.
