Teenage Rampage

A spring morning at Columbine High School, Colorado, 1999. By the afternoon, 12 of its schoolchildren and one teacher lay dead, gunned down by two of it's pupils. Cases such as Columbine are occurring with increasing regularity and guns are not always involved. In Japan in 1998, a 13-year old schoolboy murdered his teacher in a frenzied knife attack - one of many similar crimes that has shocked that country. In Britain street crime has escalated beyond our worst fears, and teenagers account for a large proportion of violent robberies in their desperation to steal must-have items like mobile phones and sports clothes. What is happening in society that young people are running amok, fuelled by hatred and nihilism? Crime expert Antonio Mendoza investigates this worldwide problem and comes up with some shocking findings.
