In line with the theories of psychologist Sigmund Freud, this could be interpreted as a shift from our normal civilized ego to the primitive, instinctive part of the psyche, which Freud called the id. According to Freud, the id is the site of our desires and drives, our emotion and aggression, and it demands instant gratification. The id is normally held in check by the ego, but is always liable to break through, especially when our inhibitions are loosened by alcohol or drugs.
Outside normal restraints, some holidaymakers allow their id to express itself as soon as they pass through security. And once they become intoxicated, the id is completely dominant, and liable to cause mayhem.
Banning alcohol from airports may sound draconian. But given that there are so many factors that encourage anti-social behavior, it is difficult to think of any other solution. In a situation when boundaries break down, leading to possible chaos, a legal boundary may be the only hope.
