As an unofficial NRA-spokesperson, I want to leave a few remarks on the subject:
1. This incident clearly shows that violent video games leading to violence and aggression is nothing but a myth. It's obviously the contrary that is true, for it was exactly the absence of violent games that caused this kid's violence.
2. While other american kids already have a chance to kill their 2 year old sisters at the age of 5 with their little Crickett rifles, this poor boy had to wait until he was 11 before he got his first real gun. We have long pointed out that such irresponsible behaviour from parents could cause these kids to suffer from G.A.S. (gun absence syndrome), a severe disease the medical branch of the NRA has recently discovered and is trying to raise awareness for.
3. If only a single law-abiding kindergarden-teacher had preventively killed that little non-law-abiding satan with her law-abiding tank or nuclear bomb, all this wouldn't have happened.
