So, ignoring this "father's" startling lack of knowledge about the game his son plays (there certainly are zombies, but the game isn't /about/ them), I just have one question for him: Who left the gun in an unlocked container that's in reach of a 9-year-old child? Or maybe you did lock-up the gun, but Minecraft gave him the key? Please explain this chain of logic you used to come upon the conclusion that some piece of software on a computer is responsible for your child having unattended access to a gun; never mind what he did after gaining said access.
Also, I think it's completely absurd that the BOY is getting in trouble for this. He is NINE FREAKING YEARS OLD! He doesn't know what he did! He probably just thought the gun was cool and wanted to show it off to his buddies. He's a kid, that's how they think (which is to say, not completely thoroughly). He probably wasn't even planning to use the damn thing!
Why, in any news post I can find on this, has no one pointed the finger at the "man" who was supposed to be in charge in this house? Why is no one asking him "Why did you leave a gun unattended with a child in the house?" Why isn't anyone charging HIM for his child bringing a gun into school? Meanwhile he's just tap-dancing all over the lasted buzz craze (if this happened 50 years ago, you know he'd be blaming comics or rock music) and apparently getting-off scott free.
I think that's the thing that REALLY has me pissed about this. I'm used to video games getting scapegoated. It's ignorant, and completely baseless (and I honestly laughed at how much the dad sounds like Hank Hill, because that's just so fitting), but I'm used to it. No no, what pisses me off is that the KID is facing THREE criminal charges over this! He is in risk of having so much shit in his life fucked-up because his DAD couldn't be responsible. Meanwhile, what is the dad getting slapped with? His gun got taken away. And that's it, that I can find.
