Well ofcourse most kids manage to grow up to be normal people despite violent media but there are many people who have committed violent acts cite violent media as their inspiration- Charles Manson being a classic example. You think it mere co-incidence that teen gang violence is pandemic at the same time violent-filled rap music fills their ears?
Well tell me this Bob- why then is there so much violence in America? Why is our per-capita murder rate far in excess of every country in Europe? This is not idle speculation- this is hard cold fact documented in crime statistics.
If exposure to violent media is not the cause- if all our guns is not the cause- then what is?
