That you're writing from Europe, and speaking English has a lot to do with American guns in the last century eh? Oh, twice right? Besides, like a media that is freer to write what it wants (just because people write it don't mean the majority believes it, or even cares about it), they trust us with guns. And, in its own, very weird, but not if you think about it, way I think the US is a lot less casually violent then just about anyplace else I've ever been (except Canada).
And its not like those parents do anything to keep those kids out of the spotlight. Brad Pitt and AJ make far more than enough money to make sure that nobody, anywhere, ever knew anything about their kids.* But the fact that both mom and dad are world class attention whores. Matter of fact alone they each earn a spot in the Top Five Attention Whores of All Time List, together, they're a straight-up Cat5 Hurricane of Attention Whoredom. They, the parents, Brad and AJ invite this crap and they ought to be held to blame for it. But of course that kid is going to join either the Lindsey Lohen Trainwreck of the Week Club, or they might end up being able to handle all that stuff so well they end up like Jamie Lee Curtis. Or they could drop out of all that stuff entirely and get a PhD in Anthropology or something. But at any rate, this is not the media's fault nearly as much as it's Brad and AJs fault.
* - I can think of tons of parents just as famous and we don't know squat about their kids, most people don't even know their names.
