The Columbine high school massacre took place in April 20, 1999 at
             Columbine High School in Jefferson County near Littleton, Colorado, United
             States, when two teenage students, Eric Harris and Dylan Klebold, executed
             a planned attacked, killing 12 other students and a teacher before killing
             themselves (Wikipedia, 2004). It is believed to be the worst school
             After the shootings, the media painted a picture of the murderers as
             outcast "nerds" who were unpopular and teased by much of the school's
             population (Wikipedia, 2004). However, later reports revealed that both
             Harris and Klebold had both a close circle of friends and a wider informal
             social group. It was also revealed that anti-gay epithets were directed at
             them, although their actual sexual orientation was unknown; both had

             clique called the "Trenchcoat Mafia" in which they wore heavy black trench
             coats. By the time of the shootings, most of the major members of the group
             had already either graduated or dropped out of Columbine.
             Since the murders, there have been a variety of theories attempting to

             popular theory is that the boys, who were known as the "Trench Coat Mafia
             outcasts" took revenge against the bullies who had made school miserable
             for them. A second conclusion is that the massacre was inexplicable: It is
             impossible to understand what drove them to such horrific violence.
             However, recently, the FBI and its team of psychiatrists and psychologists
             came to an entirely different conclusion (Cullen, 2004). These experts say
             that they understand what motivated Harris and Klebold to execute such a
             crime, and their explanation is different and more troubling than the two
             conclusions that were previously most widely believed. Three months after
             the crime took place, the FBI held a meeting ...
