One in a million

Recently, someone made it to my blog by searching for the term, "percentage of ammunition used in crimes"

Let me help you on that:

First let me say that there is no way to know, since many crimes involving ammunition are unreported, like shooting in prohibited areas, poaching, and the like. If you are talking about violent crimes, like robbery, this is again problematic since the police do not report how many shots are fired unless they strike someone.

Each year, there are approximately 10 billion rounds of ammunition sold in the United States.

In the year 2007 (the latest year for which data is available), according to the FBI, there were 15,972 murders in the United States,and 68% of these murders were committed with firearms. Therefore, have a total of 10,860 homicides in which a shot was fired.

This relates to 1 bullet in 920,810 being used in a homicide. Your odds of being killed by any particular bullet are less than the odds of you dying by being bitten by a rabid squirrel in New York's Central Park.
