I dont see anything American about this story.
Average time for murder in America is 71 months.

The reason for the light amount of years for "murder" in the U.S., is because murder in the U.S., is put into categories of seriousness, looking into the causes. You have: Involuntary manslaughter, voluntary manslaughter, 2nd degree murder and 1st degree murder. As most so-called murders fall into the first two categories, the sentences tend to be lighter (drunk driving accidents, careless/negligent behavior that results in death, et cetera). Thus, while someone died as the result of some stupid action(s), the sentence given is to teach a lesson, as well as punish, not put them away for the rest of their lives.
