Everybody cheats. Whether it’s the taxi driver who tricks a visitor and takes them the long way round, or the shop assistant who doesn’t give the correct change, or the police officer who accepts a bribe (贿赂) – everybody’s at it. Cheats in the nest include the scientist whose research was based on fake data, the game show competitors who worked with a friend in the audience or win a million pounds, and the doctor who made up his qualifications and wasn’t really a doctor at all. Everybody cheats; nobody’s playing the game.

Is cheating acceptable, a natural way of surviving and being successful? Or is it something that should be frowned on, and young people discouraged from doing? If it’s the latter how can we explain to children why so many bend the rules?

Take sport for example. The Word Cup was filled with cheating. Whether diving, pretending to be hurt or denying a handball, footballers will do anything for a free – kick or a penalty shot. France striker Henry denied cheating to win the free – kick which led to his side’s second goal in their 3 – 1 victory over Spain. Many footballers, however, are often putting it on. Whatever the nationality there’s one common ploy: the player rolls over holding their leg, ankle or head seeming to be in great pain. As a result a yellow card and / or free – kick is given for the foul and then, a few seconds later, the player is up and about as if nothing had happened ! The ref (裁判) may be taken in by it but youngsters watching the game aren’t. they also see their heroes getting away with it.

Of course it’s not just football. In 1998 the Tour de France, the world’s greatest cycling event, was hit by a drug – taking scandal (丑闻). The 40 bottles of forbidden drugs found with the Fustian team caused a massive investigation that almost caused the Tour to be abandoned. One rider, Veronique, was banned for 9 months. He claimed: “You have cheats in sport, just as you do in business – there will always be people trying to take a short cut. At least we’re not turning a blind eye to the problem, which other sports are.”

Is it all unavoidable? There’s huge pressure on all athletes to perform for their fans and for their sponsors. It’s success, money and power that rule professional sport rather than an honest at tempt to do the best one can.

Meanwhile companies around the world are losing billions of dollars to fake products. From cut price CDs and DVDs to sportswear, cheap fake products are everywhere. It has become socially acceptable to buy fake Gucci bags and illegal copies of films. If parents are doing this, their children will follow.

So perhaps it’s not surprising that around the world more pupils than ever are caught cheating during exams. In one case missing exam papers were put up for sale on the Internet. In another, widespread cheating took place by pupils using their mobile phones to receive tested answers. They blame the pressure put on them to do well in exams. It doesn’t help that their role models are also cheats. Surely we can’t complain when we’re setting such a bad example.

Despite increased airport security since September 11th, 2001, the technology to scan both passengers and baggage for weapons and bombs remains largely unchanged. Travellers walk through metal detectors and carry-on bags pass through x-ray machines that superimpose colour-coded highlights, but do little else. Checked-in luggage is screened by "computed tomography", which peers inside a suitcase rather like a CAT scan of a brain. These systems can alert an operator to something suspicious, but they cannot tell what it is.

More sophisticated screening technologies are emerging, albeit slowly. There are three main approaches: enhanced x-rays to spot hidden objects, sensor technology to sniff dangerous chemicals, and radio frequencies that can identify liquids and solids.

A number of manufacturers are using "reflective" or "backscatter" x-rays that can be calibrated to see objects through clothing. They can spot things that a metal detector may not, such as a ceramic knife or plastic explosives. But some people think they can reveal too much. In America, civil-liberties groups have stalled the introduction of such equipment, arguing that it is too intrusive. To protect travellers ’modesty, filters have been created to blur genital areas.

Machines that can detect minute traces of explosive are also being tested. Passengers walk through a machine that blows a burst of air, intended to dislodge molecules of substances on a person’s body and clothes. The air is sucked into a filter, which instantaneously analyses it to see whether it includes any suspect substances. The process can work for baggage as well. It is a vast improvement on today’s method, whereby carry-on items are occasionally swabbed and screened for traces of explosives. Because this is a manual operation, only a small share of bags are examined this way.

The most radical of the new approaches uses "quadrupole resonance technology". This involves bombarding an object with radio waves. By reading the returning signals, the machines can identify the molecular structure of the materials it contains. Since every compound—solid, liquid or gas—creates a unique frequency, it can be read like a fingerprint. The system can be used to look for drugs as well as explosives.

For these technologies to make the jump from development labs and small trials to full deployment at airports they must be available at a price that airports are prepared to pay. They must also be easy to use, take up little space and provide quick results, says Chris Yates, a security expert with Jane’s Airport Review. Norman Shanks, an airport security expert, says adding the new technologies costs around $100,000 per machine; he expects the systems to be rolled out commercially over the next 12 months. They might close off one route to destroying an airliner, but a cruel certainty is that terrorists will try to find others.
