...yet a 3 year old girl shot and killed her 2 year old brother... by manipulating the action and chambering a live round.

It's magic! Oh oh oh, it's magic, you know! (Sorry, that was crass, in light of the tragedy)...

But why won't the press really make an effort to get it right? Story here: Girl, 3, fatally shoots 2-year-old brother in Utah home* - NY Daily News

One explanation is of course that it's a NY paper... And they haven't ever even seen a gun... let alone know any nomenclature...
