Media , marketers , politicians , youth workers and researchers have been implicated in perpetuating the fear of youth . Since young people in developed countries are expected to stay out of the workforce , any role for them outside that of consumer is potentially threatening to adults . Selling safety to parents and teachers has also been a driving force , as home security systems , cellphones , and computer surveillance usage is marketed to parents ; and x-ray machines , metal detectors and closed-circuit television are increasingly sold to schools on the premise that young people are not to be trusted . These steps are in spite of the fact that experience consistently shows that monitoring youth does little to prevent violence or tragedy : the Columbine High School massacre occurred in a building with video surveillance and in-building police
