Saw this on the Times Online and thought I'd post it here for the enjoyment of all - well, the enjoyment of most of us. :D
If we want to stay safe, we need to be smarter. The first step is to put aside our qualms about passenger profiling
Philip Baum
The terror threat has changed greatly but airport security is still stuck in the past, combating the terrorism of the 1960s and 1970s. Worse still, the antiquated approach to security is aiding and abetting terrorists. The huge queues caused at checkpoints as staff check that mummy’s make-up is put into a plastic bag create an ideal target for suicide bombers: why try to board a flight when you can blow up thousands in the terminal?
The security checkpoints we know today first became widely deployed in the late 1960s and early 70s. They proved their effectiveness in the United States in tackling hijackings of flights to Cuba. Then the hijackers were armed with handguns, knives or grenades. The archway metal detector and the X-ray machine were perfect for detecting dense, metallic objects carried on the person or in baggage. More than 40 years later, the same technologies are the workhorse of the airline passenger screening process.
But the archway metal detector cannot find explosives — plastic or liquid in form — or any weapons made out of ceramic, wood, glass or polycarbonate. And while significant improvements have been made to X-ray machines they have yet to prove effective in detecting improvised explosive devices.
Nonetheless, we take a bizarre degree of satisfaction that we now screen all luggage using an unproven technology. The best that can be said is that these archaic tools act as a deterrent. But if we are serious about security, we need to think more boldly and look elsewhere to learn some useful lessons.
In 1968 an El Al aircraft was hijacked from Rome to Algiers by members of the Popular Front for the Liberation of Palestine. Following that incident, the Israelis introduced two measures: they deployed sky marshals on every flight and profiled passengers before they boarded, with the aim of identifying passengers with malign intent. No El Al aircraft has since been successfully hijacked.
We need to introduce profiling. But whenever it is proposed, it is shot down as racist: “Doesn’t it mean we’ll be picking on young Middle Eastern or Asian men?”
But one only needs to look to the Israeli experience to appreciate that, if that were the case, the system would have failed. When Japanese Red Army terrorists attacked Lod Airport in 1972, the Israelis realised that the system had to be modified to identify “intent” through behavioural analysis, rather than focus on target groups. And it worked. In 1986 Israeli security agents identified a pregnant Irish woman as a potential threat to an El Al flight bound from London Heathrow to Tel Aviv.
She was far from being the stereotypical threat, yet she was unwittingly carrying an improvised explosive device that her lover had infiltrated into her bag. The bag, by the way, had been X-rayed without the bomb being detected. That incident heralded the introduction of the “Who packed your bags?” question.
In 2001 Richard Reid, the shoebomber, was prevented from boarding a flight from Paris to Miami because security agents had suspicions about him, providing further proof of the benefits of profiling; he returned the next day and managed to board his flight. Luckily, he failed to detonate his device.
Profiling already takes place at airports all the time. Customs and immigration agents intercept people on a daily basis — but at the end of a flight. They know the signs to look for. So why, when our lives are at stake, do we not screen people using this proven, common-sense methodology before people board a flight?
The answer is that the regulators want to treat everybody the same. In doing so, they are making security predictable and easier to penetrate. The regulators want a system that they can test, but gut feeling can’t be tested.
So what would a profiler see as “cause for concern”: it’s not simply the nervous passenger biting his fingernails or young Muslim men travelling solo. It is a summary of a host of factors — everything from clothing, behaviour, baggage, accompanying persons, ticket and passport data, confidence and to what extent the suspect is typical of passengers flying on a given airline, on a given route, on a given day. From these clues, an experienced profiler can build up a picture of a passenger.
If we were serious about profiling, it would allow security staff to use new technology, such as body scanners based on X-ray or millimetre wave imaging, that would be impractical to use on everyone in terms of cost and time. We could also start screening people at the boarding gate. This would allow security staff to better profile passengers. At present the screeners are viewing passengers bound for a host of destinations in the same light, even though passengers bound for Sydney differ from those going to Reykjavik, and those heading to Bangkok are different from those flying to Lagos.
Drug traffickers, especially “body packers” (who swallow or vaginally or anally insert their illicit loads) manage to circumvent airport security daily with quantities of narcotics that far exceed the minimum weight for an explosive charge — only to be picked up by customs professionals. These traffickers want to live. What will we do when a terrorist, who wants to die, carries his or her device internally on to an aircraft? Start deploying gynaecologists at checkpoints?
No, but we need to wake up. Our current screening process is fundamentally flawed because it is concerned with what people are carrying rather than what their intent is. There is no reason for every typical family going on a package holiday or business traveller heading for a meeting, who act and look the part, to be asked to remove their shoes and belts for inspection. And the expanding list of prohibited items diverts the attention of screeners from the real objective: finding metal and liquid-free terrorists.
I don’t advocate the Israeli approach. It’s unworkable for most international airports. But unless we start injecting a dose of common sense into the security process, we’ll do what we’ve always done — be reactive rather than proactive, allowing the terrorists and misguided civil libertarians to set the timetable.
