Don't bother to knock - Editorials & Commentary - International Herald Tribune

The U.S. Supreme Court on Thursday substantially diminished Americans' right to privacy in their own homes. The rule that police officers must "knock and announce" themselves before entering a private home is a venerable one, and a well-established part of Fourth Amendment law. But President George W. Bush's two recent Supreme Court appointments have now provided the votes for a 5- to-4 decision eviscerating this rule.

So, cops can just come on in.. no need to "knock and announce". Why don't we all just live outside, speak on a phone system which uses a central mainframe to record us, have RFID tags implanted in our necks, and give DNA samples? Would that make it easier for the gov't to watch over us?
