You know what I think... the stepdad shot the kid and blamed it on the kid accidentially shooting themself.
Here's why: For one thing it's actually a little ahrd to point a gun at yourself and pull the trigger, it's very awkward and harder on the muscles ESPECIALLY for a 3yr old. The gun is heavy, handguns are solid steel and not very 3-yr old friendly. A burgler? What a crock of crap, what are the chances? And then you just leave the loaded gun on the table with 3-yr old running around? I don't think so, even a complete idiot isn't that stupid.
I think this step dad is going to try and sue Nintendo for making their gun look similar to a real gun. I bet $10 on it. Either that or he hates the stupid step kid and this was a logical way out for a piece of crap like him, or both to be honest.
Toughts? I just don't believe all those peices fell in place perfectly and a 3yr old was able to point a gun at themselves and then think it was a good idea (or even able) to try and pull the trigger.
