Jon sent me a link to this post at Reason.com, discussing the odd court decisions which seem to indicate that you have no right to privacy, but that the police do:
Such incidents have led to a national conversation about the propriety of videotaping cops, even as dashboard cameras have become standard in squad cars. There seems to be some tension in the assumption that, as Graber’s lawyer put it, “the officer has a privacy expectation, but the motorist doesn’t.”
That asymmetry has been underscored by recent rulings over global positioning systems. Last year the Virginia Court of Appeals said Fairfax County police did not violate a suspect’s right to privacy when, without a warrant, they surreptitiously put a GPS device on his vehicle to track his movements. Individuals have no expectation of privacy on the public streets, the court ruled — a position also taken by the Ninth Circuit in California.
Yet this past January, Kathy Byron, a member of Virginia’s House of Delegates, introduced legislation that would have forbidden the use of GPS tracking devices for the purpose of following political candidates. People running for public office “are still entitled to some privacy,” she argued.
Even more disturbing is the steady increase in what the police are allowed to do without a warrant or even suspicion of criminal activity:
U.S. border-patrol agents often search the phones and computers of American citizens who cross the border — routinely “accessing email accounts, examining photographs and looking through personal calendars,” according to The Constitution Project, a watchdog group. “In some cases, electronic devices were confiscated for as long as a year.” And in Michigan, the State Police have high-tech forensic devices enabling them to download information from the cell phones of stopped motorists — something they have been doing without a warrant.

Soon Americans might have no right to expect privacy even in the privacy of their own homes. Earlier this month the U.S. Supreme Court ruled 8-1 that police officers may force their way into your domicile without your consent, without a warrant, and without what are usually referred to as “exigent circumstances” — e.g., someone inside the home yelling for help. The case, Kentucky v. King, concerned an incident in which police officers chasing a drug suspect ran into an apartment building, smelled marijuana, heard noises they thought might indicate someone was destroying evidence — and broke down the wrong door. This, said the Supremes, was perfectly fine.
