Former Senator Joseph Lieberman recently charged that mistakes by U.S. security agencies were responsible for failing to stop the Boston Marathon bombing. I recently wrote about how mass surveillance makes this kind of recrimination inevitable, because once a government agency spies on a person, they become in a sense responsible for any actions that that person takes. To paraphrase Colin Powell, we might sum it up as “You surveil him, you own him.”

I recently came across a good analogy for why it’s deceptively hard for security agencies to detect and stop out-of-nowhere terrorist attacks like the Boston bombing—and why mass surveillance isn’t likely to help. It comes from the book The Drunkard’s Walk: How Randomness Rules Our Lives, by the physicist and writer Leonard Mlodinow, in a discussion of Brownian motion.

Brownian motion, you may recall, is the random jiggling of molecules in a liquid or other substance. A dye molecule floating in a seemingly still glass of water will randomly move about, covering about an inch in three hours, buffeted by random collisions with the smaller water molecules that surround it.

What would it take to actually explain the motion of that molecule? This is where the parallel to anti-terrorism efforts comes in. Mlodinow points out, “In any complex string of events in which each event unfolds with some element of

New documents from the FBI and U.S. Attorneys’ offices paint a troubling picture of the government’s email surveillance practices. Not only does the FBI claim it can read emails and other electronic communications without a warrant—even after a federal appeals court ruled that doing so violates the Fourth Amendment—but the documents strongly suggest that different U.S. Attorneys’ offices around the country are applying conflicting standards to access communications content (you can see the documents here).

Last month, in response to a Freedom of Information Act request, the ACLU received IRS documents indicating that the agency’s criminal investigative arm doesn’t always get a warrant to read Americans’ emails. Today we are releasing these additional documents from other federal law enforcement agencies, reinforcing the urgent need for Congress to protect our privacy by updating the laws that cover electronic communications.

The FBI and Electronic Communications: Where’s the Warrant?

The documents we received from the FBI don’t flat out tell us whether FBI agents always get warrants, but they strongly suggest that they don’t.

In 2010, the Sixth Circuit Court of Appeals decided in United States v. Warshak that the government must obtain a probable cause warrant before compelling email providers to turn over messages to law enforcement. But that decision only applies in the four states covered by the Sixth Circuit, so we filed our FOIA request to find out whether the FBI

We’ve been doing a fair amount of thinking about the implications of consumer wearable cameras like Google Glass, and I’m sure we’ll have more to say in this space on the subject. But meanwhile, we’re pleasantly surprised to report a very trenchant analysis of the technology’s implications for our privacy by none other than Michael Chertoff. Writing on CNN’s web page, the former DHS chief writes,

So, who owns and what happens to the user's [video] data? Can the entire database be mined and analyzed for commercial purposes? What rules will apply when law enforcement seeks access to the data for a criminal or national security investigation? For how long will the data be retained? ….

Even those who might be willing to forgo some degree of privacy to enhance national security should be concerned about a corporate America that will have an unrestricted continuous video record of millions.

What is to prevent a corporation from targeting a particular individual, using face recognition technology to assemble all uploaded videos in which he appears, and effectively constructing a surveillance record that can be used to analyze his life?

Chertoff says he’s inclined to think that government regulation may be needed. I haven’t seen Chertoff say anything about the threat of pervasive government surveillance, which would make him a kind of anti-libertarian on privacy—in favor of restricting corporations, but not the government. For the average, relatively powerless person trying to live their life, the threat comes from both directions.

What could be warmer and fuzzier than “trust”? Between two human beings, it’s a hard-won bond that binds them together. In society, it is a currency that helps create a prosperous and efficient economy and culture, as thinkers such as Francis Fukuyama and Bruce Schneier have argued. But recently the word has taken on a new cast of ambiguity, and seems to be fast becoming the newest entry in the lexicon of Orwellian formulations, along with such once purely warm and positive words such as “security,” “defense,” and “intelligence.”
