Comment expliquer le nombre de tueries aux États-Unis?

Nous le savions déjà, mais le graphique qui coiffe ce billet est particulièrement éloquent et montre bien que le cas américain est unique. On cherche depuis des années à expliquer le nombre de tueries aux États-Unis et si les variantes sont nombreuses il y a une constante entre les études: le nombre astronomique d'armes aux États-Unis.

 "Perhaps, some speculate, it is because American society is unusually violent. Or its racial divisions have frayed the bonds of society. Or its citizens lack proper mental care under a health care system that draws frequent derision abroad.

These explanations share one thing in common: Though seemingly sensible, all have been debunked by research on shootings elsewhere in the world. Instead, an ever-growing body of research consistently reaches the same conclusion.

The only variable that can explain the high rate of mass shootings in America is its astronomical number of guns."
