There have been media scapegoats for violent juvenile behaviour for years. In the 70s it was comic books, 80s it was
music, 90s they said TV was responsible, and now they've turned on videogames. Some children have violent
tendencies because of their innate personalities and because of their environmental factors. Seeing or enacting violence
in a videogame setting could be a trigger for violent actions, however if a child (or adult) has these tendencies then
there are many factors that could set them off. I think it is the responsibility of the parent to recognise the signs
and get help for their child before they hurt anyone or themselves, and using videogames as a scapegoat isnt helping the
problem at all.
However, the game genre, Rockstar in particular, isn't really helping their image. Rockstar routinely makes the
most violent and bloody games possible, which then have blanket advertising on networks and timeframes when children are
most likely to be watching. These games are rated M, and it is up to the parent to decide whether or not their kid can
play, but I think some of these games go too far to be advertised for alongside cartoons aimed at young children.
Sorry to get off on a tangent for a bit there, the bottom line is that the responsibility of these actions lies on the
child, though at 17 he is old enough to be tried as an adult.
