The Right to Privacy is a myth, like the seperation of church and state. The only "privacy" you are granted is that by the 4th amendment - the protection against unreasonable search and seizure(basically, being arrested/searched without a warrant). There are also some federal regulations and laws towards how police can get evidence which deals with the "expectation of privacy," but that's about it.
Also, consitutional rights do matter, just that some people are losing sight of that fact. The Bush administration, for example, lost sight of the fact that the entire purpose of our government is first and foremost to protect the innocent - not to punish the guilty.
In a national poll that was handed around my campus, an astonishing number(it was somewhere between 20-40% for each - I can't remember the exact numbers) of high school students thought that free speech was being protected too much, and thought that newspaper articles should be federally regulated. That kind of thing scares me.
