Since the election, the newspapers and Internet have been flooded with unsolicited advice for President-elect Barack Obama. I'll go ahead and add mine.

[...]

And by "revamp," I mean "start over." Most security experts agree that the rigmarole we go through at the airport is mere security theater, designed not to make us safer, but to make us feel safer by making it increasingly inconvenient to fly. TSA's approach to security is too reactionary -- too set on preventing attacks and attempted attacks that have already happened. And please, whatever you do, resist the temptation to let TSA workers unionize. Security from terror attacks should be a federal jobs program. You need the authority to fire underperforming screeners quickly and effortlessly. Three game-changing possibilities to head up TSA: security guru Bruce Schneier, Cato Institute security and technology scholar Jim Harper, or Ohio State University's John Mueller.

Although I'd be happy to see either Jim or John with it.

I don't want it because it's too narrow. I think the right thing for the government to do is to give the TSA a lot less money. I'd rather they defend against the broad threat of terrorism than focus on the narrow threat of airplane terrorism, and I'd rather they defend against the myriad of threats that face our society than focus on the singular threat of terrorism. But the head of the TSA can't have those opinions; he has to take the money he's given and perform the specific function he's assigned to perform. Not very much fun, really.

But I'd be happy to advise whoever Obama choses to head the TSA.

The job of the nation's CTO would be more interesting, but I don't think I want it, either. (Have you seen the screening process?)

To fix this, airport security has to make a choice. If something is dangerous, treat it as dangerous and treat anyone who tries to bring it on as potentially dangerous. If it's not dangerous, then stop trying to keep it off airplanes. Trying to have it both ways just distracts the screeners from actually making us safer."

Doesn't it just make sense?!

There are two classes of contraband at airport security checkpoints: the class that will get you in trouble if you try to bring it on an airplane, and the class that will cheerily be taken away from you if you try to bring it on an airplane. This difference is important: Making security screeners confiscate anything from that second class is a waste of time. All it does is harm innocents; it doesn't stop terrorists at all.

Let me explain. If you're caught at airport security with a bomb or a gun, the screeners aren't just going to take it away from you. They're going to call the police, and you're going to be stuck for a few hours answering a lot of awkward questions. You may be arrested, and you'll almost certainly miss your flight. At best, you're going to have a very unpleasant day.

This is why articles about how screeners don't catch every -- or even a majority -- of guns and bombs that go through the checkpoints don't bother me. The screeners don't have to be perfect; they just have to be good enough. No terrorist is going to base his plot on getting a gun through airport security if there's decent chance of getting caught, because the consequences of getting caught are too great.

Contrast that with a terrorist plot that requires a 12-ounce bottle of liquid. There's no evidence that the London liquid bombers actually had a workable plot, but assume for the moment they did. If some copycat terrorists try to bring their liquid bomb through airport security and the screeners catch them -- like they caught me with my bottle of pasta sauce -- the terrorists can simply try again. They can try again and again. They can keep trying until they succeed. Because there are no consequences to trying and failing, the screeners have to be 100 percent effective. Even if they slip up one in a hundred times, the plot can succeed.

The same is true for knitting needles, pocketknives, scissors, corkscrews, cigarette lighters and whatever else the airport screeners are confiscating this week. If there's no consequence to getting caught with it, then confiscating it only hurts innocent people. At best, it mildly annoys the terrorists.

On the other hand, it's probably a smart idea to screen screeners when they walk through airport security when they aren't working at that checkpoint at that time. The reason is the same reason you should screen everyone, including pilots who can crash their plane: you're not screening screeners (or pilots), you're screening people wearing screener (or pilot) uniforms and carrying screener (or pilot) IDs. You can either train your screeners to recognize authentic uniforms and IDs, or you can just screen everybody. The latter is just easier.

Bruce Schneier is chief security technology officer of BT. His new book is Schneier on Security.

From The Canadian Press:

“Continued inspections across the country have revealed that garbage and other items … are still being dropped inside the top panel openings of some X-ray machines,” says a bulletin issued earlier this year by the Canadian Air Transport Security Authority.

“Likewise, warning labels and hazard warning signs are being damaged and are sometimes completely removed from the units.”

The rebuke, obtained under the Access to Information Act, is the second time officers have been warned about dropping junk into the X-ray scanners. An earlier bulletin in August 2006 raised the same issue.

“Effective immediately, screening personnel caught performing any above-listed act, or similar act of vandalism to CATSA equipment will be immediately restricted from performing all screening functions.”

Any offending officer could be permanently removed from the job, the document says.

Next time you fly via a Canadian airport see if the screeners can toss out an empty coffee cup or wrapper for ya. Just for giggles.

It's easy to laugh and move on. How stupid can these people be, we wonder. But there's a more important security lesson here. Security screening is hard, and every false threat the screeners watch out for make it more likely that real threats slip through. At a party the other night, someone told me about the time he accidentally brought a large knife through airport security. The screener pulled his bag aside, searched it, and pulled out a water bottle.

It's not just the water bottles and the t-shirts and the gun jewelry -- this kind of thing actually makes us all less safe.

In the study, Dr Eichele and his colleagues asked participants to repeatedly perform a "flanker task" -- an experiment in which individuals must quickly respond to visual clues.

As they did so, brain scans were performed using functional magnetic resonance imaging (fMRI).

They found the participants' mistakes were "foreshadowed" by a particular pattern of brain activity.

"To our surprise, up to 30 seconds before the mistake we could detect a distinct shift in activity," said Dr Stefan Debener, of Southampton University, UK.

"The brain begins to economise, by investing less effort to complete the same task.

"We see a reduction in activity in the prefrontal cortex. At the same time, we see an increase in activity in an area which is more active in states of rest, known as the Default Mode Network (DMN)."

This has security implications whenever you have people watching the same thing over and over again, looking for anomalies: airport screeners looking at X-ray scans, casino dealers looking for cheaters, building guards looking for bad guys. It's hard to do it correctly, because the brain doesn't work that way.

Black lights will help screeners inspect the ID cards by illuminating holograms, typically of government seals, that are found in licenses and passports. Screeners also are getting magnifying glasses that highlight tiny inscriptions found in borders of passports and other IDs. About 2,100 of each are going to the nation's 800 airport checkpoints.

The closer scrutiny of passenger IDs is the latest Transportation Security Administration effort to check passengers more thoroughly than simply having them walk through metal detectors.

[...]

More than 40 passengers have been arrested since June in cases when TSA screeners spotted altered passports, fraudulent visas and resident ID cards, and forged driver's licenses. Many of them were arrested on immigration charges.

ID checks have nothing to do with airport security. And even if they did, anyone can fly on a fake ID. And enforcing immigration laws is not what the TSA does.

In related news, look at this page from the TSA's website:

We screen every passenger; we screen every bag so that your memories are from where you went, not how you got there. We're here to help your travel plans be smooth and stress free. Please take a moment to become familiar with some of our security measures. Doing so now will help save you time once you arrive at the airport.

I know they don't mean it that way, but doesn't it sound like it's saying "We know it doesn't help, but it might make you feel better"?

And why is this even news?

So Jason -- looking every bit the middle-aged man on an uneventful trip to anywhere -- shows a boarding pass and an ID to a TSA document checker, and he is directed to a checkpoint where, unbeknown to the security officer on site, the real test begins.

He gets through, which in real life would mean a terrorist was headed toward a plane with a bomb.

To be clear, the TSA allowed CNN to see and record this test, and the agency is not concerned with CNN showing it. The TSA says techniques such as the one used in Tampa are known to terrorists and openly discussed on known terror Web sites.

Also relevant: "Confessions of a TSA Agent":

The traveling public has no idea that the changes the TSA makes come as orders sent down directly from Washington D.C. Those orders may have reasons, but we little screeners at a screening checkpoint will never be told what the background might be. We get told to do something, and just as in the military, we are expected to make it happen -- no ifs, ands or buts about it. Perhaps the changes are as a result of some event occurring in the nation or the world, perhaps it's based on some newly received information or interrogation. What the traveling public needs to understand the necessity for flexibility. If a passenger asks us why we're doing something, in all likelihood we couldn't tell them even if we really did know the answer. This is a business of sensitive information that is used to make choices that can have life changing effects if the information is divulged to the wrong person(s). Just trust that we must know something that prompts us to be doing something.

I have no idea why Kip Hawley is surprised that the TSA is as unpopular with Americans as the IRS.
