A historian at Ohio State University argues yes in a new book called "American Homicide ." 一位俄亥俄州立大学历史学家一本名为《美国谋杀》书中坚称是。
Randolph Roth studied homicide rates over the past four hundred years in parts of the United States and western Europe. andolph Roth 研究过 400 年前的部分美国和西欧的谋杀率。
The Justice Department says rates in recent years fell to levels last seen in the middle of the nineteen sixties. 司法部称近年来的谋杀率已经降到了 19 世纪中期才能看到的水平。
Still, murder rates in the United States have generally been among the highest among Western democracies since the middle of the nineteenth century. 然而,自从 19 世纪中期以来美国的谋杀率通常是西方民主国家中最高的。
