The report was written by a committee whose members include William Perry, a professor at Stanford University; Charles Vest, the former president of MIT; W. Earl Boebert, a retired senior scientist at Sandia National Laboratories; Cynthia Dwork of Microsoft Research; R. Gil Kerlikowske, Seattle's police chief; and Daryl Pregibon, a research scientist at Google.

They admit that far more Americans live their lives online, using everything from VoIP phones to Facebook to RFID tags in automobiles, than a decade ago, and the databases created by those activities are tempting targets for federal agencies. And they draw a distinction between subject-based data mining (starting with one individual and looking for connections) compared with pattern-based data mining (looking for anomalous activities that could show illegal activities).

But the authors conclude the type of data mining that government bureaucrats would like to do--perhaps inspired by watching too many episodes of the Fox series 24--can't work. "If it were possible to automatically find the digital tracks of terrorists and automatically monitor only the communications of terrorists, public policy choices in this domain would be much simpler. But it is not possible to do so."

A summary of the recommendations:

• U.S. government agencies should be required to follow a systematic process to evaluate the effectiveness, lawfulness, and consistency with U.S. values of every information-based program, whether classified or unclassified, for detecting and countering terrorists before it can be deployed, and periodically thereafter.

• Periodically after a program has been operationally deployed, and in particular before a program enters a new phase in its life cycle, policy makers should (carefully review) the program before allowing it to continue operations or to proceed to the next phase.

• To protect the privacy of innocent people, the research and development of any information-based counterterrorism program should be conducted with synthetic population data... At all stages of a phased deployment, data about individuals should be rigorously subjected to the full safeguards of the framework.

• Any information-based counterterrorism program of the U.S. government should be subjected to robust, independent oversight of the operations of that program, a part of which would entail a practice of using the same data mining technologies to "mine the miners and track the trackers."

• Counterterrorism programs should provide meaningful redress to any individuals inappropriately harmed by their operation.

• The U.S. government should periodically review the nation's laws, policies, and procedures that protect individuals' private information for relevance and effectiveness in light of changing technologies and circumstances. In particular, Congress should re-examine existing law to consider how privacy should be protected in the context of information-based programs (e.g., data mining) for counterterrorism.

Here are more news articles on the report. I explained why data mining wouldn't find terrorists back in 2005.

Here's my idea. If you're a company, add every one of your customers to the list. That way, none of your competitors will be able to cold call them.

Charlie Rose:  
And so when you look at where we are going, there seems to be two issues that are apparent to me at least, risk and leverage.  We just lost sight of risk and leverage of what was appropriate?

Warren Buffett:  
Yeah.  Again, because it pays off for a while.  You know, you can lose leverage, and it's the only way a smart guy can go broke.  If you owe money, you can't pay them out.  You just pay for everything, you do smart things, you eventually get very rich.  If you do smart things and use leverage and do one wrong thing along the way, it could wipe you out, because anything times zero is zero.  But it's reinforcing when the people around you are doing it successfully, you're doing it successfully, and it's a lot like Cinderella at the ball.  I mean you know at midnight everything is going to turn to pumpkins and mice; right?  But if the evening goes along, I mean, you know, the guys look better all the time, the music sounds better, it's more and more fun, you think why the hell should I leave at quarter of 12.  I'll leave at two minutes to 12.  But the trouble is, there are no clocks on the wall.  And everybody thinks they're going to leave at two minutes to 12.

Charlie Rose:  
And should wise people have known better?

Warren Buffett:  
People should always know better.

Charlie Rose:  
Yeah.

Warren Buffett:  
I mean people -- people don't get -- they don't get smarter about things that get as basic as greed and you can't stand to see your neighbor getting rich.  You know you're smarter than he is, and he's doing these things, you know, and he's getting rich, and your spouse is getting unhappy with you because you aren't doing -- pretty soon you start doing it.  And so you get what I call the natural progression, the three Is.  The innovators, the imitators, and the idiots.  And that's what happens.  Everybody just kind of goes along.  And you look kind of silly if you disagree.  I mean, you know, you could have these crazy Internet valuations in the late 1990s, but they prove themselves out in the market.  The next day they were selling for more than they were the day before, and people said, you know, you're crazy if you don't get in on this.  So it's very human.  Now, with housing it's something even more dramatic than that, because most people aspire to own their own home.  And if you really think that houses prices are going to go up next year and the year after, you feel if I don't buy it this year, I'm going to have to buy it next year.  That's not true of an Internet stock.  But it's true of a home.  And when somebody makes it very easy for you to do it by saying you don't really have to put up my money, you can lie about your income a little, or we'll give you 100 percent mortgage, you're going to do it, because everybody that's done it has been proven right.  You have what they call social tools, and, you know, you're going to feel like an idiot if you didn't do it, because the house cost more.

Warren Buffett:  
Oh, I think confidence will come back.  I will tell you this.  This country is going -- be living better ten years from now than it is now.  It will be living better in 20 years from now than ten years from now.  The ingredients that made this country, you know, the miracle of the world -- I mean we had a seven for one improvement in the average American standard of living in the 20th century.  Now, we had the great depression, we had two world wars, we had the flu epidemic.  You know, we had oil shock.  You know, we had all these terrible things happen.  But something about the American system unleashed more and of a potential to human beings over that hundred years so that we had a seven for one improvement in -- there's never been any -- I mean, you have centuries where if you've got a 1 percent improvement, then it's something.  So we've got a great system.  And we've got more productive capacity now than we ever have.  The American worker is more productive than he's ever been.  We've got more people to do it.  We've got all the ingredients for a sensational future.  It's just that right now the athlete's on the floor.  But we -- this is a super athlete.
