In what appears to be one of Edward Snowden’s final revelations, the former CIA and NSA agent has demonstrated conclusively that the National Security Agency has collected and analyzed the contents of emails, text messages, and mobile and landline telephone calls from nine Americans for every one foreign person it has targeted.

This puts the lie to the government’s claims that it has only collected metadata -- identifying markers such as phone numbers and email addresses -- and not content from unsuspecting and unsuspected Americans. It puts the lie to the government’s claims that it has studiously avoided prying into the private lives of Americans, in whom it has no intelligence-related or lawful interest. And this puts the lie to the government’s contentions and the opinions of judges of the secret Foreign Intelligence Surveillance Court that the NSA’s spying is somehow lawful, constitutional and helpful.

We now know that the government has failed effectively to refute the Snowden claims that it has collected and maintained for future access massive amounts of personal materials about nearly all people in America since 2009. This includes the metadata and content of nearly every telephone call, email and text message made, sent or received in the U.S., as well as nearly every credit card bill, utility bill and monthly bank statement of nearly every person in the U.S.

This was accomplished through the issuance of general warrants by FISA court judges. General warrants do not particularly describe the place to be searched or the person or thing to be seized as the Constitution requires. General warrants authorize the bearer to use the power of government to search wherever he wishes. The use by British troops of general warrants was a principal motivation for the American Revolution, and the very purpose and literal wording of the Fourth Amendment was to outlaw and prohibit them.

Nevertheless, in their lust to appear muscular in our constitutionally sad post-9/11 era, politicians from both major political parties have defied the plain meaning and universally accepted history of the right to privacy and reverted to these odious instruments so condemned by the nation’s founders and the Constitution’s framers.

The recent Snowden revelations showed that about 900,000 innocent Americans -- including President Obama himself -- were subjected to heavy NSA scrutiny. This was done by NSA agents who knew that the subjects of their scrutiny were not the targets of their investigation.

How could that happen? It happened because the FISA court meets in secret, where the NSA has no opposition and the court has no transparency. This volatile mix has resulted in that court's granting well over 99 percent of NSA applications, including the “hop” rule implicated in the scrutiny of innocent Americans. In NSA-speak, a hop is a jump from one telephone conversation to another using a common phone.

In the sterile, isolated and secret environment of the FISA court -- where even the judges cannot keep records of their own decisions -- NSA agents and lawyers have persuaded judges to permit spying on people who are six hops from a target. Thus, by way of illustration, if A is a target and speaks with B, the NSA can listen to all of B’s conversations, even those not with A. The leap from A to B is one hop, and the NSA gets six, so it can listen to any C who has spoken to B, any D who has spoken to any C, any E who has spoken to any D, any F who has spoken to any E and any G who has spoken to any F.

The 900,000 innocent Americans whose private and personal lives have been subjected to NSA scrutiny -- including the examination of their photographs, intimate personal behavior, medical and financial needs -- consist of those who are within six hops from a target; in the illustration above, that would be every B, C, D, E, F and G whom the NSA can find. According to Snowden, there is no effort made by the NSA to minimize the scrutiny of those who are in the B-G category -- even though the chances that any of them are in cahoots with A are extremely remote, particularly once the NSA gets beyond B.

But remoteness does not trouble the NSA, and neither does the Constitution. Remoteness is a serious constitutional and practical problem. It violates the rights of known innocents, as the NSA has no constitutional or lawful authority to spy on any non-targets and FISA court judges have no power to authorize that spying. It also consumes the time and resources of NSA agents, whose job it is to find terror plots.

Is it any wonder that the Boston Marathon bombers discussed their plans with friends using their cellphones and the NSA missed it?

Is it any wonder that when Gen. Keith Alexander, who ran the NSA for five years, was asked under oath how many plots his agents had uncovered with their spying on all Americans, he replied 57 and then the next day changed that reply to three and then was unable or unwilling to identify the supposed three?

Is it any wonder that the two non-FISA court federal judges who scrutinized all this both found that it has uncovered no plots?

When the government sees or hears all, it knows all. And when the people tolerate a government that knows all, they will be afraid to be themselves. And the joy of being and expressing oneself is the very reason we have a Constitution designed to restrain government.

James Madison warned that the loss of liberty rarely happens in one great event but rather happens gradually, over time, resulting from the actions of government officials who claim to be fortifying security. He practically predicted today’s events. The violations of our rights are obvious, undenied and undeniable. Yet what Madison probably feared most, he did not articulate: Once lost, liberty is lost forever.
