Finally, we’ve mentioned the amount of money USA invests in “behaviour detection officers”. Although the practice is not highly effective as detecting lies is a complex process that becomes even harder in the situation where a great majority of people is innocent, we wouldn’t go so far to completely discredit this practice. Quite the contrary, there are some improvements in this field that are still to be implemented on a larger scale. This is the case with the Controlled Cognitive Engagement, that is comprised of numerous techniques that use conversational cues as their main focus point. In one research it proved to be as much as 24 times more effective than its traditional variation (Dando, 2014). This is one of the things Israel could learn from America, especially considering constant threats that come from all sides. Detecting people trying to smuggle weapons, explosive devices and substances would be much easier if Israel is to implement Controlled Cognitive Engagement.

The last improvement is even more needed with knowing that Israeli security checks are notoriously long and tedious (Huxley, 2017). Numerous questionings could be precluded if the aforementioned effective technique is employed.

To conclude, there is much divergence between the two countries in the field of airport security. Of course, they intersect at some points, as we’ve seen, but differences are more than conspicuous. This conclusion stems from the differences between the most urgent problems that the two countries face. Although the US invests large sums of money into baggage checking and lie detection, their Israeli counterparts are currently much more focused on this aspect. On the other hand, the US has to coordinate a vast number of airports, and make sure that each and every one is up to the best standards.
