6,000,000 cubic kilometers of molten material - enough to cover the continental U.S. at a one mile depth.
I don't think the submitter understands math. One mile is about 1.6 km, so 6,000,000 km^3 of lava would cover an area of 3,750,000 km^2. Yet when I check Wikipedia (and Princeton, and the other top 5 Google results), they all say the Contiguous United States has an area of just over 8,000,000 km^2. That's an awfully big mistake. I hope the actual Stanford paper is of better quality than the Slashdot summary.
The document indicates the passenger tracking operation was a trial run of a powerful new software program CSEC was developing with help from its U.S. counterpart, the National Security Agency. In the document, CSEC called the new technologies "game-changing," and said they could be used for tracking "any target that makes occasional forays into other cities/regions."
The CBC notes early in the article that the spy agency:
is supposed to be collecting primarily foreign intelligence by intercepting overseas phone and internet traffic, and is prohibited by law from targeting Canadians or anyone in Canada without a judicial warrant.
Predictably, CSEC's chief is quoted saying that they aren't allowed to spy on Canadians, so therefore they don't. As observed by experts consulted for the story, that claim is equivalent to saying that they collect the data but we're to trust that they don't look at it."
