This clearly looked like an accident and not some 9 year old going "I'm a marine!" and shooting people. Honestly, that kind of a comment makes no sense and you should feel ridiculous for mentioning it at all.
It's not supposed to make sense, I was taking the **** out of every news story that blames video games whenever there is a shooting somewhere.
The fact I have to explain this very obvious joke makes me sad, I hope you feel suitably ridiculous for failing to grasp it. Even if you think the joke is a bit crap, it wasn't exactly difficult to spot was it? How many times have you heard someone suggest CoD reduces gun crime again?
I'm Israel, he's Palestine, its more fun when you pick sides.
