In other words, since theoretically almost anyone might possibly be guilty of anything, it's not really an unconstitutional policy that makes a joke of the 4th Amendment to gather data on everyone -- with the blessing of a secret court, accountable to no one:
WASHINGTON — In more than a dozen classified rulings, the nation’s surveillance court has created a secret body of law giving the National Security Agency the power to amass vast collections of data on Americans while pursuing not only terrorism suspects, but also people possibly involved in nuclear proliferation, espionage and cyberattacks, officials say.
The rulings, some nearly 100 pages long, reveal that the court has taken on a much more expansive role by regularly assessing broad constitutional questions and establishing important judicial precedents, with almost no public scrutiny, according to current and former officials familiar with the court’s classified decisions.
The 11-member Foreign Intelligence Surveillance Court, known as the FISA court, was once mostly focused on approving case-by-case wiretapping orders. But since major changes in legislation and greater judicial oversight of intelligence operations were instituted six years ago, it has quietly become almost a parallel Supreme Court, serving as the ultimate arbiter on surveillance issues and delivering opinions that will most likely shape intelligence practices for years to come, the officials said.
And since the members of the court are appointed by Chief Justice John Roberts, and they don't even have the bother of listening to opposing arguments, it's even better!
Last month, a former National Security Agency contractor, Edward J. Snowden, leaked a classified order from the FISA court, which authorized the collection of all phone-tracing data from Verizon business customers. But the court’s still-secret decisions go far beyond any single surveillance order, the officials said.
“We’ve seen a growing body of law from the court,” a former intelligence official said. “What you have is a common law that develops where the court is issuing orders involving particular types of surveillance, particular types of targets.”
In one of the court’s most important decisions, the judges have expanded the use in terrorism cases of a legal principle known as the “special needs” doctrine and carved out an exception to the Fourth Amendment’s requirement of a warrant for searches and seizures, the officials said.
The special needs doctrine was originally established in 1989 by the Supreme Court in a ruling allowing the drug testing of railway workers, finding that a minimal intrusion on privacy was justified by the government’s need to combat an overriding public danger. Applying that concept more broadly, the FISA judges have ruled that the N.S.A.’s collection and examination of Americans’ communications data to track possible terrorists does not run afoul of the Fourth Amendment, the officials said.
Even though this is not the Supreme Court and they don't really have the authority to create their own precedents. Shadow government, anyone?
