Stewart Baker has this post at Volokh Conspiracy, "HIPAA is an arguably well-intentioned privacy law that seems to yield nothing but 'unintended' consequences."  I'm not quite as cynical on HIPAA as Stewart, and I wouldn't have said "arguably" or put "unintended" in quotes.  He is right that the law has had numerous bad consequences, though, including this gem from the Daytona Beach News-Journal:

In the name of patient privacy, a Daytona Beach, Fla., nursing home said it couldn't cooperate with police investigating allegations of a possible rape against one of its residents.
