Desensitization/ Culmination Theory

This theory concerns my topic as many teenagers are less sensitive towards shootings and death due to their over exposure towards these issues produced in media texts. The desensitization theory is basically how over exposure of a particular idea shown through a media product can make individuals less sensitive. In the case of my project... ...Violence and gun culture is desesitized for many teenagers because of their over exposure to hip hop music and the guns that are publicised as acceptable alongside dominant hip hop artists. Therefore some teenagers take gun culture for granted as a result of desensitization. Could this be the case with Jamie Bulger?? The children were so young, surely their perceptions on harming others and murder were desensitized by their over exposure from media texts?
