I dunno...I've read some really horrifying baby murder stories from the U.S. here on this board over the past few weeks. It seems like there are psychopaths all over the place these days, in every country.
Yes, there are some horrific murders in the US that cross all racial and religious backgrounds (well, I would wager most of the perps don’t get religion until they are on death row...)
But in no case have I seen someone slit the throat of a child relative in a supermarket. Decapitation is pretty much exclusive to fundamentalist islamic nutcases (unless you go back in time 200+ years to france)
