Where did the kid get money for a $50 game? how did he get to the store on his own? why arent his parents teaching him its wrong to lie? Where are they when he is playing the game? Why dont they talk to the parents of friends when he goes to a friends house? How come they arent doing the occasional check between the matresses for contraband like M rated games?
Shall I continue?
This is all about parental responsibility. The ratings are there, there reviews are all over the internet, and the back of the box will have a description of exactly what is being bought. Its the parents who just buy whatever their kid asks for without investigating ,and lets their kid play alone in their room for hours on end, never checking on them, that is to blame for the behavior of their offspring.
When a child commits a crime, its the fault of the parents for not being there and for not raising their kid right.
