boy 8 kills gran after playing video games

according to sky news "An eight-year-old boy intentionally shot and killed his grandmother minutes after playing the violent video game Grand Theft Auto IV, US authorities said." 
well first of all he was white, secondly he was america and third of all he was a white american which means access to guns from a young age is normal especailly in the are which the fatal shooting took place( louisana ) which is down the south of america where a couple decades ago lynchings where taking place on a daily , anyway the question here is where video games to blame for his grandmothers untimely demise, well.. , partly, here we have an 8 year old boy who is somewhat ignorant and nieve and who probably cant comprehend how the world works. 

now dont get it twisted there are some f@cked up kids out there and this is definatly not the first case of a child murderer however....., here he used a gun, and the question is how did he find the weapon used, how did he know how to load it and if it was loaded who taught him how to aim it, video games may have given the boy the perception that death is only temporary and that a headshot is an honarable thing however who ever left this 8 year old with the means to murder his own grandma with a gun is the real one at fault here 

Most 8 year old boys in their spare time these days are playing on games consoles in their spare time, but i doubt most 8 year olds are playing games with an age rating ten years over theirs which glorifies violence which may have helped to warp the mind of this young boy into taking the course of actions which lead to hid grandmothers death, in this case video games had a part in corrupting this child but it was at the fault of the parent or guardian who was not regulating the media which the child was accessing, if the child had been watching 18+ action movies with high levels of violence maybe he would have done the same thing
