Ambiguous test:

Okay. This looks like the place to put my comment, which is this:

If a person living in a rural setting (farm, forest, isolated village, etc) hears a shot fired, the assumption generally is that a deer, rabbit, or something of the kind is the target. On the other hand, a person living in an urban setting (such as Detroit) is more likely to assume that the target is another person. Flaws aside, I think that may be the reason for the results.
