A retired CIA agent and guest blogger writes....

The chief concern we should have, of course, about the newly revealed NSA spying program is that it is being done, in violation of existing laws, without clear authorization or oversight.

But we should also be concerned with this as just another stupid idea that is not likely to result in any useful intelligence. The following is from a blog discussing whether or not this approach is likely to find anything of value.

NSA Sweep "Waste of Time," Analyst Says

It'd be one thing if the NSA's massive sweep of our phone records was actually helping catch terrorists. But what if it's not working at all? A leading practitioner of the kind of analysis the NSA is supposedly performing in this surveillance program says that "it's a waste of time, a waste of resources. And it lets the real terrorists run free."

Re-reading the USA Today piece, one paragraph jumped out:

This kind of data collection from phone companies is not uncommon; it's been done before, though never on this large a scale, the official said. The data are used for 'social network analysis,' the official said, meaning to study how terrorist networks contact each other and how they are tied together.

So I called Valdis Krebs, who's considered by many to be the leading authority on social network analysis -- the art and science of finding the important connections in a seemingly-impenetrable mass of data. His analysis of the social network surrounding the 9/11 hijackers is a classic in the field.

Here's what Krebs had to say about the newly-revealed NSA program that aims to track "every call ever made": "If you're looking for a needle, making the haystack bigger is counterintuitive. It just doesn't make sense."

"Certain people are more suspicious than others," he adds. They make frequent trips back-and-forth to Afghanistan, for instance. "So you start with them. And you work two steps out. If none of those people are connected, you don't have a cell. Because if one was there, you'd find some clustering. You don't have to collect all the data in the world to do that."

The right thing to do is to look for the best haystack, not the biggest haystack. We knew exactly which haystack to look at in the year 2000 [before the 9/11 attacks]. We just didn't do it...

The worst part -- the thing that's most disappointing to me -- is that this is not the right way to do this. It's a waste of time, a waste of resources. And it lets the real terrorists run free.
